Abstract: Enhanced biometric authentication combines a user's inherent biometric data with the user's password, code, or other secret glyph. For example, the user's finger makes an input on a touchpad. An image of a fingerprint is extracted from the input, along with the user's password, code, or other secret glyph. In one input, then, the user's finger serves two authentication schemes for increased security.

Abstract: Methods and apparatus to certify digital signatures are disclosed. An example method includes retrieving, from a first database, a first geographical location associated with an identification number associated with a network device and identified in a request to certify a digital signature, comparing the first geographical location associated with the identification number to a second geographical location to verify the second geographical location, and in response to the verification of the second geographical location and to a comparison of (a) biometric information associated with a user associated with the request and (b) stored biometric information, instructing a certificate issuer to certify the digital signature to indicate an authenticity of the digital signature.

An example method includes retrieving, from a first database, a first geographical location associated with an identification number associated with a network device and identified in a request to certify a digital signature, comparing the first geographical location associated with the identification number to a second geographical location to verify the second geographical location, determining that the first geographical location matches the second geographical location, and certifying the digital signature to indicate an authenticity of the digital signature based on the verification of the second geographical location and a comparison of (a) biometric information associated with a user associated with the request and (b) stored biometric information.

Abstract: Enhanced biometric authentication is achieved by combining a user's inherent biometric data with the user's knowledge of a secret glyph. In one embodiment, a touchpad is provided on which the user may use a finger to indicate a plurality of strokes that form a distinct glyph. Image stabilization may be used to extract a readable fingerprint from the strokes, and the glyph and finger print are matched to a stored profile. The glyph may be one or more alphanumeric characters that represent a password. The user can then enter the password on the touch pad with his finger. If the fingerprint and password both match, the user is authenticated.

Abstract: A method includes receiving at a first computer a new certificate which is to replace an old certificate associated with the first computer and associating by the first computer the new certificate with the first computer. In response to the first computer associating the new certificate with the first computer, the first computer accesses an email address book of the first computer having information identifying a second computer as having received the old certificate to determine from the information that the second computer is to associate the new certificate in place of the old certificate with the first computer. In turn, the first computer transmits the new certificate to the second computer for the second computer to associate the new certificate with the first computer.

Abstract: Methods and apparatus to certify digital signatures are disclosed. An example method includes receiving a request to certify a digital signature from a user, receiving information about a physical characteristic of the user, comparing the information about the physical characteristic to stored physical characteristic information, and based on the comparison, at least one of certifying the digital signature based on the comparison or requesting certification of the digital signature based on the comparison.

Abstract: A method for using an update engine to promulgate a transaction tool to a recipient. The method may include the steps of: generating a transaction tool operation request signal wherein the transaction tool operation request signal includes a request for a new transaction tool and/or an updated transaction tool, transmitting the transaction tool operation request signal to a transaction tool issuer, receiving a transaction tool update signal from the transaction tool issuer wherein the transaction tool update signal includes a new transaction tool and/or an updated transaction tool, determining the recipient, and transmitting the transaction tool update signal to the recipient.
