PROVIDING CONTENT ORIGIN VERIFICATION

Abstract

A computer-implemented method for content origin verification is provided. The computer-implemented method includes obtaining a signing certificate for a peripheral input device. The computer-implemented method further includes receiving input data from the peripheral input device and a digest associated with the input data. The computer-implemented method further includes processing the received input data as standard input. The computer-implemented method further includes verifying an origin of the standard input, in which the verifying includes applying the signing certificate for the peripheral input device to the digest and checking contents of the digest against the standard input.
