13. A computer system comprising:
-
means for processing digital data; and means for storing machine-readable data, the means for storing machine readable data having contained at least one non-certificate data block, at least one prior certificate, a new certificate which certifies a combination of less than all of a union of the at least one non-certificate data block and the at least one prior certificate, and a user interface for selecting the new certificate and for rendering the new certificate in human readable form; wherein the new certificate comprises a digital signature means, the digital signature means verified by inputting the combination of less than all of a union of the at least one non-certificate data block and the at least one prior certificate to means for verifying the signature, the means for verifying the digital signature means executing on the means for processing digital data. - View Dependent Claims (14, 15, 16)
