摘要： A security element comprises at least one oscillating circuit (Ol-On) and a digital signature (2). Each oscillating circuit (Ol-On) comprises a capacitor (Cl-Cn) as resonance frequency setting element wherein the capacitor (Cl-Cn) consists of two electrodes (8, 10) which are spaced apart from each other and a dielectric (9) that is sandwiched between the two electrodes (8, 10). The capacitor (Cl-Cn) of each oscillating circuit has a random capacitance value which randomness is caused by a non-uniform thickness (d) of the dielectric (9) and/or by an inhomogeneous dielectric material. The digital signature (2) comprises reference values indicative for the resonance frequencies (fl - fh) of the oscillating circuits wherein the reference values are digitally signed with a secret key.

摘要： The present invention relates to a system and a method of verifying the identity of an individual by employing biometric data associated with the individual (603), wherein privacy of said biometric data (X, Y) is provided. A helper data scheme (HDS) is employed to provide privacy of the biometric data. The present invention is advantageous for number of reasons. First, processing of security sensitive information is performed in a secure, tamper-proof environment (601, 604, 606) which is trusted by the individual. This processing, combined with utilization of a helper data scheme, enables set up of a biometric system where the biometric template is available in electronic form only in the secure environment. Moreover, electronic copies of the biometric templates are not available in the ecure environment permanently, but only when the individual offers her template to the sensor.
摘要翻译：本发明涉及通过采用与个体相关联的生物特征数据（603）来验证个人身份的系统和方法，其中提供所述生物特征数据（X，Y）的隐私。使用辅助数据方案（HDS）来提供生物特征数据的隐私。出于多个原因本发明是有利的。首先，在由个人信任的安全的防篡改环境（601,604,606）中执行安全敏感信息的处理。该处理结合使用辅助数据方案，可以建立生物识别系统，其中生物特征模板仅在安全环境中以电子形式提供。此外，生物特征模板的电子副本在永久环境中不可用，但只有当个人将模板提供给传感器时。

摘要： The invention relates to a tamper-resistant semiconductor device comprising a substrate (5) comprising an electronic circuit arranged on a first side thereof. An electrically- conductive protection layer (50, 50a, 50b) is arranged on a second side of the substrate (5) opposite to the first side. At least three through-substrate electrically-conductive connections (45) extend from the first side of the substrate (5) into the substrate (5) and in electrical contact with the electrically- conductive protection layer (50, 50a, 50b) on the second side of the substrate (5). A security circuit is arranged on the first side connected to the through- substrate electrically-conductive connections (45) and is arranged for measuring at least two resistance values (R12, R23, R34, R14, R13, R24) of the electrically- conductive protection layer (50, 50a, 50b) through the through-substrate electrically-conductive connections (45). The security circuit is further arranged for comparing the measured resistance values (R12, R23, R34, R14, R13, R24) with reference resistance values.

摘要： A wearable accessory controls (103) and provides security for a pill delivering medical substances and services. An initialization procedure allows decryption information (814) to be loaded into the accessory for each pill and/or decryption information (818) about the accessory to be loaded into the pill. The pill preferably sends encrypted messages to the accessory and the accessory preferably sends encrypted messages to the pill. The pill operates only when the proximity of the accessory is verified or authenticated during the operation of the pill, preferably at frequent intervals. Where the pill is no longer useful, its information can be deleted (1205) from memory in the accessory or other controlling device.

摘要： The invention relates to a method (MA; MB) of testing similarity of a first DNA-related data to a second DNA-related data under encryption based on a feature-based encryption scheme in conjunction with a secure two-party computation scheme is provided. Employing a secure two-party computation scheme allows testing similarity of the first 5 DNA-related data to the second DNA-related data. The outcome of this comparison, i.e. the test result, may be made available to an authorized party. If the test result is negative, no information about the first DNA-related data and the second DNA-related data is revealed. If the test result is positive, only limited information about the first DNA-related data and the second DNA-related data may be revealed to an authorized party.

摘要： The present invention relates to a method of converting an encrypted data set into an encryption of individual bits representing the data set. Further, the invention relates to a system for converting an encrypted data set into an encryption of individual bits representing the data set. A basic idea of the present invention is to provide a protocol in which it is possible to divide an encryption of a data set in the form of e.g. a biometric feature, such as a number x, where x e {0, 1, ..., n-1 }, into an encryption of respective bits x 0 , x 1 , ..., x t-1 forming the number x, where t is the number of bits of the number n-1, without leaking any information about x or its bits x 0 , x 1 , ..., x t-1 Hence, the present invention enables splitting of the encryption [[x]] into the respective encrypted bits [[x 0 ]], [[x 1 ]], ..., [[x t-1 ]] forming the encrypted number x=?I=1 n x i 2 i .
摘要翻译：本发明涉及一种将加密的数据集转换成对代表数据集的各个位进行加密的方法。此外，本发明涉及一种用于将加密的数据集转换成代表数据集的各个位的加密的系统。本发明的基本思想是提供一种协议，在该协议中可以将例如数据集的形式的数据集的加密划分成多个部分。将诸如x的生物特征，其中xe {0,1，...，n-1}分解成相应比特x _{0 ，x _{1 ，...，x t-1 形成数字x，其中t是数字n-1的位数，而不泄露关于x或其位x _{0的任何信息因此，本发明使得能够将加密[[x]]分割成各自的加密比特 [[x _{0 ]]，[[x _{1 ]]，...，[[x _{t-1 ]] 数字x =？I = 1 x _{i 2 ^{i 。}}}}}}}}
