The fingerprint is a biomarker widely used as an identifier in security applications. However, current popular fingerprint scanners mostly detect skin surface undulation and hence are vulnerable to spoofing attacks. The proposed approach leverages THz wave penetration into the multilayered skin structure to provide a unique spectral response and enable higher security fingerprint scanning. By implementing an imaging system that scans the fingerprint using a tightly focused THz beam, we present measurement results of an in-vivo finger specimen in the 330–500 GHz range. High-resolution fingerprint images and THz frequency responses are obtained. Besides, two spoof samples are fabricated using latex for comparison. The measurement results show a noticeable discrepancy compared with real skin, which can be used to distinguish fake fingerprints (spoofs).","PeriodicalId":13258,"journal":{"name":"IEEE Transactions on Terahertz Science and Technology","volume":"14 6","pages":"874-883"},"PeriodicalIF":3.9,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142579217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experimental results demonstrate that terahertz noise with a frequency range of 200–390 GHz can be obtained with an excess noise ratio (ENR) up to 48 ± 4.3 dB, corresponding to an equivalent noise temperature exceeding 10\u0000<sup>7</sup>\u0000 K. Furthermore, the proposed noise source is used to measure the noise figure of a mature mixer product, holding the promise of generating terahertz noise at a higher frequency and with a larger bandwidth. The proposed photonic noise source possesses a high integration and raises the frequency range and the ENR of the noise spectrum to a new level.","PeriodicalId":13258,"journal":{"name":"IEEE Transactions on Terahertz Science and Technology","volume":"14 6","pages":"791-798"},"PeriodicalIF":3.9,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142579143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
