Patent number: 6996543Abstract: In order to verify the authenticity of manufactured goods, a smart tag is attached to the goods containing encrypted authentication information, such as a serial number, a description of the good's physical appearance or chemical decomposition, its color, or digital images of the good etc. The encryption procedure comprises public/private key encryption with zero-knowledge protocols. Zero knowledge protocols allow a smart tag to be authenticatable and yet be duplication resistant by allowing the verifying agent to convince him/herself that the smart tag is authentic without revealing its authentication information. The verification procedure can be done using a reader at a point of sale (POS) machine equipped with the appropriate public key and zero-knowledge protocols to decrypt the authentication information. A printed version of the serial number or other authentication information may be placed on the goods in human readable form to quickly verify the information electronically read from the smart tag.Type: GrantFiled: October 29, 1998Date of Patent: February 7, 2006Assignee: International Business Machines CorporationInventors: Don Coppersmith, Claude A. Greengard, Charles P. Tresser, Chai Wah Wu

Patent number: 6982625Abstract: An electronic event recorder for attachment to a vehicle is provided which can broadcast encrypted signature and data, thereby leaving behind an electronic version of a “fingerprint” in the event of an accident or traffic violation. The fingerprint, captured by an external data acquisition system or another vehicle so equipped, provides a history of events related to the vehicle. The event recorder is preferably integrated on a smart card and housed in a tamper proof casing. In a first mode of operation, monitoring stations along the roadways periodically send an interrogation signal, such as when radar detects that the vehicle is speeding. Upon receiving the interrogation signal the smart card transmits the vehicle's signature information to the monitoring station where it is time and date stamped along with the speed of the vehicle.Type: GrantFiled: November 25, 2003Date of Patent: January 3, 2006Assignee: International Business Machines CorporationInventors: Timothy J. Chainer, Claude A. Greengard, Charles P. Tresser, Chai W. Wu

Patent number: 6501390Abstract: The present invention provides methods and apparatus to detect and reliably record the physical history of a product including effects due to one or more of the following: 1) product use 2) handling 3) tampering and 4) environment of the product (as changes in the environment, such as excessive temperatures, humidity, or shocks, can result in degradation to a product). The apparatus includes a “smart card”, or, more generally, “smart token”, in combination with one or more sensors which record the external influences on the product and/or the environment and records those changes in an encrypted form. This information can then be verified by any individual who is equipped with a (possibly public) decryption key, but capability to modify this information, depending on the application, is restricted to those with access to the encrypting key.Type: GrantFiled: January 11, 1999Date of Patent: December 31, 2002Assignee: International Business Machines CorporationInventors: Timothy J. Chainer, Claude A. Greengard, William R. Pulleyblank, Charles P. Tresser, Chai W. Wu

Patent number: 6069955Abstract: A visible seal or label containing a serial number is placed in plain view on the product packaging. The visible label contains the serial number as well as a first public key encrypted version of the serial number. A second or hidden label inside of the package has thereon a second a second encrypted version of the serial number made using a second public key. The hidden label may be secured inside of the package out of sight or may be placed on the back of the visible label and therefore viewable through a transparent case when opened or visible when peeled off. The private keys are known only to the manufacturer. Using a corresponding public key provided by the manufacturer, the consumer, law enforcement agent, or customs inspector can verify that the encrypted version matches the serial number. An advantage to this method is that only the manufacturer can produce matching pairs.Type: GrantFiled: April 14, 1998Date of Patent: May 30, 2000Assignee: International Business Machines CorporationInventors: Don Coppersmith, Claude A.
