With a total of 3 patents to her name, Ahlgren's work has the potential to enhance the efficiency and security of portable communication devices.
Latest Patents
One of her latest patents is a method and apparatus for synchronizing databases in portable communication devices. This innovation involves calculating a checksum on a database stored in a SIM card whenever changes are made. The checksum can be stored in a mobile phone along with a change log. During synchronization, if the checksums do not match, a full synchronization process is initiated to ensure that all database records are accurately compared. If the checksums match, the synchronization can proceed more efficiently using the change log.
Another significant patent by Ahlgren is a technique for securely storing data within a memory. This technique involves encrypting data using a non-verifiable personal identifier, ensuring that the data remains secure. The encrypted data and a reminder are stored in memory, and they can only be decrypted using the same identifier, which is not stored in the memory itself. This method enhances the security of the system by preventing unauthorized access.
