Latest Patents

One of Olsen's latest patents focuses on content item encryption on mobile devices. This innovation allows applications to be stored on removable storage in an encrypted form, providing both isolation and piracy protection. Each application is encrypted using its own associated encryption key, which is generated based on the application's identifier and a master key linked to a trusted platform module of the mobile device. In another implementation, Olsen's patent describes a method where each application is encrypted using two associated encryption keys. One key encrypts binary data, such as source code, while the other key encrypts application data, including graphics and configuration files. The encryption keys are generated using the application's identifier, the master key, and identifiers of the folders where the corresponding data types are stored. The removable storage can include SD cards formatted using the FAT or exFAT file systems.

Another significant patent by Olsen involves a multi-user application executing in user privilege mode. This system allows the multi-user application to access resources of multiple users by identifying them and retrieving access tokens for each user. Each access token serves as evidence of authorization to access resources according to the user's access rights. This innovative approach enables the multi-user application to access resources without needing to execute in a system privilege mode.
