Novel fingerprint key generation method based on the trimmed mean of feature distance by Zhongtian JIA, Qinglong QIN, Li MA, Lizhi PENG

“…In recent years, biometrics has become widely adopted in access control systems, effectively resolving the challenges associated with password management in identity authentication.However, traditional biometric-based authentication methods often lead to the loss or leakage of users’ biometric data, compromising the reliability of biometric authentication.In the literature, two primary technical approaches have been proposed to address these issues.The first approach involves processing the extracted biometric data in a way that the authentication information used in the final stage or stored in the database does not contain the original biometric data.The second approach entails writing the biometric data onto a smart card and utilizing the smart card to generate the private key for public key cryptography.To address the challenge of constructing the private key of a public key cryptosystem based on fingerprint data without relying on a smart card, a detailed study was conducted on the stable feature points and stable feature distances of fingerprints.This study involved the extraction and analysis of fingerprint minutiae.Calculation methods were presented for sets of stable feature points, sets of equidistant stable feature points, sets of key feature points, and sets of truncated means.Based on the feature distance truncated mean, an original fingerprint key generation algorithm and key update strategy were proposed.This scheme enables the reconstruction of the fingerprint key through re-collecting fingerprints, without the need for direct storage of the key.The revocation and update of the fingerprint key were achieved through a salted hash function, which solved the problem of converting ambiguous fingerprint data into precise key data.Experiments prove that the probability of successfully reconstructing the fingerprint key by re-collecting fingerprints ten times is 0.7354, and the probability of reconstructing the fingerprint key by re-collecting fingerprints sixty times is 98.06%.…”

Regional differences in intercohort and intracohort trends in obesity in the USA: evidence from the National Health Interview Survey, 1982–2018 by Emma Zang, Liying Luo, Jiahui Xu

“…We address the knowledge gap by investigating net of age and period trends, how intercohort and intracohort patterns in obesity may depend on Census regions for black and white men and women.Design, setting and participants A total of 1 020 412 non-Hispanic black and white respondents aged 20–69 were included from the 1982–2018 National Health Interview Survey.Outcome measures Obesity is defined as body mass index ≥30 kg/m2 based on participant self-reported weight and height. Obesity ORs were calculated to estimate region-specific age, period and cohort patterns for each demographic group.Results Although age and period trends in obesity were similar across regions for all demographic groups, cohort patterns depended on region of residence for white women. …”

Precipitation Concentration in Highly Urbanized Regions — Case Study of Yangtze River Delta Urban Agglomeration by LIN Zequn, WANG Dayang, ZHANG Zhi, WANG Dagang

“…The Theil-Sen Median slope estimation and Mann-Kendall significance test are utilized for trend analysis,and a correlation analysis is employed to explore the relationship between urbanization levels and precipitation concentration.The results show that:① the root mean square error between the GI calculated from climate hazards Group infrared precipitation with station data (CHIRPS) and the station data results is 0.036,significantly lower than the results from CMFD data (0.067) and MSWEP data (0.083),which indicates that CHIRPS data demonstrates optimal applicability.② The unevenness of precipitation in the Yangtze River Delta urban agglomeration gradually increases from south to north,with a significant increasing trend in the central and western parts of the agglomeration.The intra-annual distribution of precipitation in the study area has become more concentrated,leading to an increased likelihood of extreme precipitation events.③ Urbanization is likely to promote the concentration of precipitation.The rapid development of cities enhances precipitation unevenness,especially in areas such as Nanjing,Wuxi,and Zhenjiang,making them more susceptible to urban flooding and related disasters.The findings of this research have practical implications for urban flood control design,urban road drainage system planning,and the development of emergency response plans for urban flood control.…”
