  • Method and system for dynamically distributing updates in a network
    Patent number: 7353511
    Abstract: A first version of a program operating at a network site is updated by automatically downloading from a remote site any update for the program in response to an automated event. A downloaded update is installed to generate a second version of the program. The second version of the program is operated at the network site in place of the first version.

  • Method and system for providing tamper-resistant executable software
    Patent number: 6567917
    Abstract: Tamper-resistant software is provided by determining an initial value of a specified property for an executable file. The executable file is then encrypted based on the initial value of the specified property. The initial value of the specified property is associated with the encrypted executable file and later used to decrypt the encrypted executable file. An execution-time value of the specified property is determined for the decrypted executable file. The execution-time value of the specified property is compared to the initial value of the specified property to determine whether tampering has occurred. The decrypted executable file is executed in response to the execution-time value of the specified property matching the initial value of the specified property.
