SIGNATURE PROGRAMS APPARATUS
Technical Examples
- A method is provided for distributing programming. A first set of programs is transmitted in real time according to a schedule of programming. A second set of programs is stored on a server, each of which is configured to be played for a user under the user's control. At least one of the first set of programs has a counterpart in the second set of programs. A notification signal is transmitted to distinguish at least one of the second set of programs on the server from programs not on the server.
- A method for determining whether a disputed electronic signature is that of a purported signator includes the steps of (a) creating in a single step an ink on paper signature and an identical electronic signature of the purported signator; (b) verifying that the ink on paper signature is consistent with known ink on paper signatures of the purported signator; and (c) comparing the disputed electronic signature with the electronic signature of the purported signator to determine whether the disputed electronic signature is that of the purported signator.
- A multiple use ticket generating method is disclosed which enables a recipient to obtain signatures for arbitrarily many (correctly formed) messages after only one interaction with the signer. The method provides a blind signature in a ticket, the signature having a multiple use with a built-in expiration. Then, the method develops a blinding value for the signature in a reproducible computation using a seed key substantially known only to the issuer of the ticket. The method implements a new class of signature schemes almost as efficiently as do previous one-time restrictive blind signature methods.
- Apparatus, methods, and articles of manufacture consistent with the present invention provide a check validation scheme wherein a payor's signature is digitized, encrypted and embedded on the front of the check using glyphs. When the payor seeks to convert a blank check into a negotiable instrument, the user fills out the check and signs it. When the check is presented to a bank for payment, a teller using a decoding device, decodes and decrypts the digitized signature such that a human-readable image of the digitized signature can be seen on a screen for comparison with the payor's scripted signature. If the two signatures are identical, the check is honored.
- A computer-based method and system for performing header filtering of data is presented The method comprises compressing the header of a data packet to obtain a header signature and determining if the header signature matches a known header signature. If the header signature is determined to have a match, then the header signature is identified as a known header signature. A header signature may be generated using a multidimensional data compression algorithm. A compression algorithm comprises obtaining the data bits contained in each field of a typical header. Then, a header-field group that corresponds uniquely to each field is determined. Each field is replaced with the header-field group of the corresponding data bits of the field and concatenated to create a header signature.
