Latest Patents
One of Howard's latest patents is a system for accessing telephonic communications. This telephone access system utilizes a calling card encoded with a machine-readable code for both an access telephone number and a personal identification number. A reader/dialer reads the data encoded on the calling card and generates dialing tones accordingly. Once the data is entered, the calling card can be stored securely. To access the calling account, the reader/dialer emits tones corresponding to the access telephone number and personal identification number, allowing the caller to proceed with their telephonic transaction once verified.
Another significant patent is a personal security system that verifies the identity of a system user. Each user possesses a token that processes an inputted seed to generate a stored value, which is either a current seed value or a function thereof. This value changes in response to selectively generated trigger signals. The stored current seed or a selected function is outputted and inputted into a host verification unit, which compares the received and generated seed function values to verify the user.
