First Claim
Patent Images
1. A method for managing updates on a computing device, comprising:
- receiving from a second computing device file header information of a file residing on the second computing device;
generating a signature of the file based on the file header information;
responsive to the signature being absent in a plurality of signatures, transmitting to the second computing device a request for the file from the second computing device and updating the computing device using the file.
