Abstract: Methods and apparatus for verifying a boot process of a computing system are disclosed. An example computer-implemented method includes reading, by a computing system during a boot process, a header section of a read-write portion of firmware of the computing system. The example method further includes generating, using a first cryptographic hash algorithm, a message digest corresponding with the header. The example method also includes decrypting, using a first public-key, an encrypted signature corresponding with the header. The example method still further includes comparing the message digest corresponding with the header and the decrypted signature corresponding with the header. In the event the message digest corresponding with the header and the decrypted signature corresponding with the header match, the example method includes continuing the boot process. In the event the message digest corresponding with the header and the decrypted signature corresponding with the header do not match, the example method includes halting the boot process.

Abstract: Users can navigate and manipulate content, such as by scrolling a document or selecting content in the document, by using various touch inputs that indicate a behavior that the user is trying to perform. In order to improve the user interface experience for a user, embodiments analyze touch inputs to determine when a user would like to perform a navigational jump and then execute such a jump, based on the specific touch inputs involved.
