Abstract

A seal against intrusions into the identity of an object is formed by a capsule that is attached to the object and contains a chip in which identifying data are stored and can be recalled by means of a terminal for an identity check. The seal may include a tie loop incorporating a semiconductor-based delay line or a light-conducting glass fiber cable and can be designed to register intrusive manipulations of the capsule or tie loop.

Description

Claims (33)

  1. A device for protecting the identity of an object, usinga chip (8) encased in a capsule (1)that can be attached to the object to be protected and cannot bedetached from the object without destroying functionallyessential features,
    in which non-erasable data that define its identity and therebythe identity of the object can be storedand
    from which at least a part of the data can be interrogatedthrough a terminal when a check is performed by authorizedindividuals to determine whether, since the tine when the datain question were stored, manipulations occurred with the aim ofviolating the identity of the object,
    wherein the capsule (1) consisting of a neutral material notinterfering with the function of the identity protection isconnected to the object through an identity-protectionloop (4, 5) in such a manner that it is possible todetermine whether a manipulation has been performed with the capsuleand the chip or with the identity-protection loop that leadsinto and is functionally connected with the capsule,characterisedin that the identity-protectionloop is designed and arranged in relation to the chip in such amanner that sequential light signals or electrical signalsissuing from chip (8) and entering the one end of the identity-protectionloop that is connected to chip (8), after passingthrough the loop and reentering the chip at the other end of theloop, can be registered in chip (8) and, if necessary, comparedwith each other for the purpose of determining the condition ofthe loop,
    wherein the identity-protectionloop is formed by a light conductor and the chip (8)is mounted on a polymer film (25) or the like with conductivetraces by which the chip is connected with the two ends (4, 5)of the light conductor by way of semiconductors representing alight source (26) and light sensors (27).
  2. A device for protecting the identity of an object, usinga chip (8) encased in a capsule (1)that can be attached to the object to be protected and cannot bedetached from the object without destroying functionallyessential features,
    in which non-erasable data that define its identity and therebythe identity of the object can be storedand
    from which at least a part of the data can be interrogatedthrough a terminal when a check is performed by authorizedindividuals to determine whether, since the time when the datain question were stored, manipulations occurred with the aim ofviolating the identity of the object,
    wherein the capsule (1) consisting of a neutral material notinterfering with the function of the identity protection isconnected to the object through an identity-protectionloop (4, 5) in such a manner that it is possible todetermine whether a manipulation has been performed with the capsuleand the chip or with the identity-protection loop that leadsinto and is functionally connected with the capsuler,characterisedin that the identity-protectionloop is designed and arranged in relation to the chip in such amanner that sequential light signals or electrical signalsissuing from chip (8) and entering the one end of the identity-protectionloop that is connected to chip (8), after passingthrough the loop and reentering the chip at the other end of theloop, can be registered in chip (8) and, if necessary, comparedwith each other for the purpose of determining the condition ofthe loop,
    wherein the identity-protection loop is designed as asemiconductor chain in the form of a delay line with a pluralityof delay elements, the number of which determines the point intime when the pulse that was emitted from chip (8) returns tothe chip after having passed through the chain.
  3. The device according to claim 1 or 2, whereinnot only the non-erasable data that define its identity and therebythe identity of the object can be stored but also other datathat can be altered if necessary such as, e.g., the location,time, and details about the individuals involved in securing theobject and the like, through carrier-frequency transmission bymeans of a terminal, and
    new data corresponding to a possible change inthe object can be stored and also interrogated through theterminal in a case where authorized individuals accessed theprotection in the intervening time, wherein
    through an antenna (9) that is connected to the chipthe non-erasable data that define the identity of the object aswell as the additional data, erasable if necessary, can beentered and stored from the outside through said carrier-frequencytransmission and can be recalled from thechip in analogous manner in case of an inspection check.
