  • Handling of the usage of software in a disconnected computing environment
    Patent number: 8745375
    Abstract: A method, computer program product and system of handling usage of software in a disconnected computing environment. A digital certificate including time frame constraints is generated, signed by a certificate authority and associated to the software. To be executed, the digital certificate previously signed must be validated by the certificate authority by checking public keys and the time frame constraints must be simultaneously satisfied in the disconnected computing environment. The use of software is controlled in disconnected computing environments and/or read-only computing environments, i.e. environments which are not modifiable or in which brought modifications are not persistent. The data collected by the software may be further encrypted and thus be controlled.
