摘要： A method for issuing an electronic identity based on previously certified electronic identity. This is accomplished by providing a method to use a previously certified identity to create another representational form for the same identity. This way the holder of a certificate can extend his or her already verified identity for other uses. The previously certified identity can be for instance so called mobile identity which is associated to a person's mobile terminal such as mobile phone. The person can show to certificate be his/her own by using the digital signature feature of the mobile terminal.

摘要： In a method and system for authenticating locally-stored program code, a first checksum is computed using the locally-stored program code, the computed checksum is compared with a second checksum known to be valid and, if the two checksums are determined to match, the locally-stored program code is deemed valid and authentic. For increased certification reliability and dependability, before computation of the first checksum a predetermined challenge is added to the stored program code, so that the first checksum is computed from the combination of the stored program code and the challenge. This enhancement enables secure use of stored program code in applications that demand high security. Users of such software may therefore rely on the authenticity of the data processed by the software and of the data and results reported on the display of a mobile phone or keyboard throughout the entire process or transaction.
