The crucial factor is the initial composition of fingermarks, because it represents the starting point of any aging model. This study mainly aimed to characterize the initial composition of fingerprints, which show a high variability between donors (inter-variability), but also to investigate the variations among fingerprints from the same donor (intra-variability). Solutions to reduce this initial variability using squalene and cholesterol as target compounds are proposed and should be further investigated. The influence of substrates was also evaluated, and the initial composition was observed to be larger on porous surface than nonporous surfaces. Preliminary aging of fingerprints over 30 days was finally studied on a porous and a nonporous substrate to evaluate the potential for dating of fingermarks. Squalene was observed to decrease in a faster rate on a nonporous substrate.", "publicationTitle": "Journal of Forensic Sciences", "publisher": "", "place": "", "date": "2011", "volume": "56", "issue": "1", "section": "", "partNumber": "", "partTitle": "", "pages": "102–108", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1111/j.1556-4029.2010.01523.x", "citationKey": "", "url": "http://onlinelibrary.wiley.com/doi/10.1111/j.1556-4029.2010.01523.x/abstract", "accessDate": "2013-04-13T14:29:33Z", "PMID": "", "PMCID": "", "ISSN": "1556-4029", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "Wiley Online Library", "callNumber": "", "rights": "2010 American Academy of Forensic Sciences.

Recent improvements in capturing techniques allow for the application of high-resolution contactless image sensors to the lifting of latent fingerprints, potentially replacing classical contact based techniques such as powdering and sticky tape lifting in the future. This technology might help police authorities to identify criminals, but it also poses privacy concerns due to its ability to capture large amounts of fingerprints. Therefore, one has to give special consideration to data privacy management. One way of promoting data privacy could be to determine the age of fingerprints in advance and to not capture fingerprints left at times irrelevant for a crime. Another way could be to determine the age of fingerprints in parallel to the investigation and securely delete fingerprint data as soon as it is found to be of age different to the crime. To this end, we explore the possible future technology of fingerprint age determination and its use for data privacy protection in a repressive application scenario at the crime scene as well as a preventive one at the airport. This will be analyzed from a technical-legal point of view in order to promote legal criteria of the German and European privacy and data protection laws.", "bookTitle": "Data Privacy Management and

of crime scene forensics, current methods of evidence collection, such as the acquisition of shoe-marks, tireimpressions, palm-prints or fingerprints are in most cases still performed in an analogue way. For example, fingerprints are captured by powdering and sticky tape lifting, ninhydrine bathing or cyanoacrylate fuming and subsequent photographing. Images of the evidence are then further processed by forensic experts. With the upcoming use of new multimedia systems for the digital capturing and processing of crime scene traces in forensics, higher resolutions can be achieved, leading to a much better quality of forensic images. Furthermore, the fast and mostly automated preprocessing of such data using digital signal processing techniques is an emerging field. Also, by the optical and non-destructive lifting of forensic evidence, traces are not destroyed and therefore can be re-captured, e.g. by creating time series of a trace, to extract its aging behavior and maybe determine the time the trace was left. However, such new methods and tools face different challenges, which need to be addressed before a practical application in the field. Based on the example of fingerprint age determination, which is an unresolved research challenge to forensic experts since decades, we evaluate the influences of different environmental conditions as well as different types of sweating and their implications to the capturing sensory, preprocessing methods and feature extraction. We use a Chromatic White Light (CWL) sensor to exemplary represent such a new optical and contactless measurement device and investigate the influence of 16 different environmental conditions, 8 different sweat types and 11 different preprocessing methods on the aging behavior of 48 fingerprint time series (2592 fingerprint scans in total). We show the challenges that arise for such new multimedia systems capturing and processing forensic evidence", "publicationTitle": "", "publisher": "", "place": "", "date": "juin 1, 2012", "volume": "", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "84360Y-84360Y", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1117/12.922701", "citationKey": "", "url": "http://dx.doi.org/10.1117/12.922701", "accessDate": "2013-04-08T10:30:12Z", "PMID": "", "PMCID": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "Silverchair", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [], "relations": {}, "dateAdded": "2013-04-08T10:30:12Z", "dateModified": "2013-04-08T10:30:12Z" } }, { "key": "QMF2DUZW", "version": 20, "library": { "type": "group", "id": 159733, "name": "Datation des traces digitales", "links": { "alternate": { "href": "https://www.zotero.org/groups/datation_des_traces_digitales", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/159733/items/QMF2DUZW", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/datation_des_traces_digitales/items/QMF2DUZW", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/159733/items/DGH9SJN6", "type": "application/json" } }, "meta": { "createdByUser": { "id": 345117, "username": "Paola Rattu", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/paola_rattu", "type": "text/html" } } } }, "data": { "key": "QMF2DUZW", "version": 20, "parentItem": "DGH9SJN6", "itemType": "attachment", "linkMode": "linked_url", "title": "Full Text PDF", "accessDate": "2013-04-08T10:30:12Z", "url": "http://proceedings.spiedigitallibrary.org/data/Conferences/SPIEP/64954/84360Y_1.pdf", "note": "", "contentType": "application/pdf", "charset": "", "tags": [], "relations": {}, "dateAdded": "2013-04-08T10:30:12Z", "dateModified": "2013-04-08T10:30:12Z" } }, { "key": "8J53WAQJ", "version": 60, "library": { "type": "group", "id": 159733, "name": "Datation des traces digitales", "links": { "alternate": { "href": "https://www.zotero.org/groups/datation_des_traces_digitales", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/159733/items/8J53WAQJ", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/datation_des_traces_digitales/items/8J53WAQJ", "type": "text/html" } }, "meta": { "createdByUser": { "id": 345117, "username": "Paola Rattu", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/paola_rattu", "type": "text/html" } } }, "creatorSummary": "Croxton et al.", "parsedDate": "2010-06-15", "numChildren": 1 }, "data": { "key": "8J53WAQJ", "version": 60, "itemType": "journalArticle", "title": "Variation in amino acid and lipid composition of latent fingerprints", "creators": [ { "creatorType": "author", "firstName": "Ruth S", "lastName": "Croxton" }, { "creatorType": "author", "firstName": "Mark G", "lastName": "Baron" }, { "creatorType": "author", "firstName": "David", "lastName": "Butler" }, { "creatorType": "author", "firstName": "Terry", "lastName": "Kent" }, { "creatorType": "author", "firstName": "Vaughn G", "lastName": "Sears" } ], "abstractNote": "The enhancement of latent fingerprints, both at the crime scene and in the laboratory using an array of chemical, physical and optical techniques, permits their use for identification.

An understanding of latent fingerprint chemistry and behaviour will aid the improvement of current techniques and the development of novel ones. In this study the amino acid and fatty acid content of 'real' latent fingerprints collected on a non-porous surface was analysed by gas chromatography-mass spectrometry. Squalene was also quantified in addition. Hexadecanoic acid, octadecanoic acid and cis-9-octadecenoic acid were the most abundant fatty acids in all samples. There was, however, wide variation in the relative amounts of each fatty acid in each sample. It was clearly demonstrated that touching sebum-rich areas of the face immediately prior to fingerprint deposition resulted in a significant increase in the amount of fatty acids and squalene deposited in the resulting 'groomed' fingerprints. Serine was the most abundant amino acid identified followed by glycine, alanine and aspartic acid. The significant quantitative differences between the 'natural' and 'groomed' fingerprint samples seen for fatty acids were not observed in the case of the amino acids.

Although fingerprint identification has been repeatedly proven as one of the most robust and definite forensic techniques, a measure of the rate at which latent fingerprints degrade over time has not been established effectively. Ideally, criminal investigators should be able not only to place any given individual at a crime scene but also be able to date the moment any latent fingerprints were deposited at the location. The present report aims to determine particular visual patterns of degradation of latent fingerprints exposed to certain monitored laboratory conditions simulating those in the field. Factors considered include temperature, relative humidity, air currents, composition of fingerprint depositions (sebaceous and eccrine), various exposures to daylight (direct, penumbra, and darkness), and type of physical substrate (glass and plastic) over a period of 6 months. The study employs a titanium dioxide-based powder as developer. Our results indicate that, contrary to common belief, certain latent fingerprints exposed to direct sunlight indoors degrade similarly to those in the dark where environmental conditions are more constant. While all sebaceous latent fingerprints on glass are still useful for identification after 6 months, diverse results are obtained with impressions on plastic; these demonstrate a much higher and faster degree of decay, making identification difficult or impossible, especially for eccrine depositions.", "publicationTitle": "International Journal of Legal Medicine", "publisher": "", "place":

Transferring imaging techniques from different application areas, such as 3D image acquisition, surface measurement and chemical analysis to the domain of lifting latent biometric fingerprint traces is an upcoming trend in forensics. Such non-destructive sensor devices might help to solve the challenge of determining the age of a latent fingerprint trace, since it provides the opportunity to create time series and process them using pattern recognition techniques and statistical methods on digitized 2D, 3D and chemical data, rather than classical, contact-based capturing techniques, which alter the fingerprint trace and therefore make continuous scans impossible. In prior work, we have suggested to use a feature called binary pixel, which is a novel approach in the working field of fingerprint age determination. The feature uses a Chromatic White Light (CWL) image sensor to continuously scan a fingerprint trace over time and retrieves a characteristic logarithmic aging tendency for 2D-intensity as well as 3D-topographic images from the sensor. In this paper, we propose to combine such two characteristic aging features with other 2D and 3D features from the domains of surface measurement, microscopy, photography and spectroscopy, to achieve an increase in accuracy and reliability of a potential future age determination scheme. Discussing the feasibility of such variety of sensor devices and possible aging features, we propose a general fusion approach, which might combine promising features to a joint age determination scheme in future. We furthermore demonstrate the feasibility of the introduced approach by exemplary fusing the binary pixel features based on 2D-intensity and 3D-topographic images of the mentioned CWL sensor. We conclude that a formula based age determination approach requires very precise image data, which cannot be achieved at the moment, whereas a machine learning based classification approach seems to be feasible, if an adequate amount of features can be provided.", "publicationTitle": "", "publisher": "", "place": "", "date": "février 9, 2012", "volume": "", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "82900Y-82900Y", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1117/12.908637", "citationKey": "", "url": "http://dx.doi.org/10.1117/12.908637", "accessDate": "2013-04-08T10:16:39Z", "PMID": "", "PMCID": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "General fusion approaches for the age determination of latent fingerprint traces", "language": "", "libraryCatalog": "Silverchair", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [], "relations": {}, "dateAdded": "2013-04-08T10:16:39Z", "dateModified": "2013-04-08T10:16:39Z" } }, { "key": "GINKN6WN", "version": 14, "library": { "type": "group", "id": 159733, "name": "Datation des traces digitales", "links": { "alternate": { "href": "https://www.zotero.org/groups/datation_des_traces_digitales", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/159733/items/GINKN6WN", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/datation_des_traces_digitales/items/GINKN6WN", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/159733/items/E9JSV3AJ", "type": "application/json" } }, "meta": { "createdByUser": { "id": 345117, "username": "Paola Rattu", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/paola_rattu", "type": "text/html" } } } }, "data": { "key": "GINKN6WN", "version": 14, "parentItem": "E9JSV3AJ", "itemType": "attachment", "linkMode": "linked_url", "title": "ScienceDirect Full Text PDF", "accessDate": "2013-04-08T10:15:35Z", "url": "http://pdn.sciencedirect.com/science?_ob=MiamiImageURL&_cid=271258&_user=946187&_pii=037907389090151N&_check=y&_origin=article&_zone=toolbar&_coverDate=1990--30&view=c&originContentFamily=serial&wchp=dGLbVlV-zSkzV&md5=e1f5191918ba30ca28d9b7ee71655204&pid=1-s2.0-037907389090151N-main.pdf", "note": "", "contentType": "application/pdf", "charset": "", "tags": [], "relations": {}, "dateAdded": "2013-04-08T10:15:35Z", "dateModified": "2013-04-08T10:15:35Z" } }, { "key": "62HJDUEX", "version": 14, "library": { "type": "group", "id": 159733, "name": "Datation des traces digitales", "links": { "alternate": { "href": "https://www.zotero.org/groups/datation_des_traces_digitales", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/159733/items/62HJDUEX", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/datation_des_traces_digitales/items/62HJDUEX", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/159733/items/E9JSV3AJ", "type": "application/json" } }, "meta": { "createdByUser": { "id": 345117, "username": "Paola Rattu", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/paola_rattu", "type": "text/html" } } } }, "data": { "key": "62HJDUEX", "version": 14, "parentItem": "E9JSV3AJ", "itemType": "attachment", "linkMode": "linked_url", "title": "ScienceDirect Snapshot", "accessDate": "2013-04-08T10:15:35Z", "url": "http://www.sciencedirect.com/science/article/pii/037907389090151N", "note": "", "contentType": "text/html", "charset": "", "tags": [], "relations": {}, "dateAdded": "2013-04-08T10:15:35Z", "dateModified": "2013-04-08T10:15:35Z" } }, { "key": "E9JSV3AJ", "version": 14, "library": { "type": "group", "id": 159733, "name": "Datation des traces digitales", "links": { "alternate": { "href": "https://www.zotero.org/groups/datation_des_traces_digitales", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/159733/items/E9JSV3AJ", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/datation_des_traces_digitales/items/E9JSV3AJ", "type": "text/html" } }, "meta": { "createdByUser": { "id": 345117, "username": "Paola Rattu", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/paola_rattu", "type": "text/html" } } }, "creatorSummary": "Baniuk", "parsedDate": "1990", "numChildren": 2 }, "data": { "key": "E9JSV3AJ", "version": 14, "itemType": "journalArticle", "title": "Determination of age of fingerprints", "creators": [ { "creatorType": "author", "firstName": "Krystyna", "lastName": "Baniuk" } ], "abstractNote": "In this paper the process of ageing of fingerprints is considered and such factors affecting the process as: chemical composition of a fingerprint trace, external influences and background material are taken into account.
