The present invention relates generally to devices for security and, in particular, to devices for attachment to objects for securing said objects and detecting whether said there has been tampering of the device attached to the object. The invention further relates to a system having the device and to a method of operating the system.
Tamper-proof products, often a sticker for sticking upon objects, are known. Such devices are limited to providing a visual indication that a seal has been broken or that a sticker has been removed. Such products are weak and fallible because careful manipulation of the product or use of heat or steam to weaken the adhesion can allow the product to be removed. Inspection often relies on a human examining the product for evidence of tampering. Human error, or corruption, is not uncommon.
Known security products are applied to objects to inhibit theft, or to prevent their use. Not only can these products be tampered with but they can be re-attached.
Even if such products are not configured for re-attachment and leave evidence of tampering behind this is often an unattractive solution for a consumer. But it can be unacceptable for high-value clothing or fashion accessories to have evidence of tampering after a product has been removed.
By way of example, attaching a tamper product to a camera to temporarily restrict its use would leave residue on the lens.
Therefore, there exists a need for an improved tamper device that addresses the problems associated with known products.

In an embodiment of the invention, the blocker 102, or body, is adapted to block the optical field of the sealing/closing element 130 for restricting the sealing/closing element 130 of capturing images. The blocker 102 is adapted to be positioned in a blocking position with respect to the sealing/closing element 130 for blocking the sealing/closing element 130 from capturing images. The tampering sensor or transducer 104 is adapted to be connected to the blocker 102 for detecting any tampering attempt of the blocker 102. The tampering sensor 104 is adapted to have a first state when the blocker 102 is in a first position and a second state when the blocker 102 is in a second position. In other words the sensor or transducer is configured to be actuateable. The first position is when the blocker 102 is in a blocking position restricting access through the sealing/closing element 130 to the object or the content of the object, whereas the second position is when the blocker 102 is in an unblocking position allowing at least partially access to the object or content of the object s through the sealing/closing element 130. The tampering sensor 104 is adapted to react differently based on whether the blocker 102 is in the first position or in the second position.
The control module, or indicator or controller 106 is adapted to be connected to the tampering sensor 104 for determining whether the tampering sensor 104 is in the first state or the second state and, based on this information, for determining whether the position of the blocker 102 has been tampered from the first blocking position to the second unblocking position. If the position of the blocker 102 is determined to be tampered, the control module 106 generates and transmits a notification signal notifying that the position of the blocker 102 has been tampered. The notification signal comprises an identifier of the device 100. The memory 108 of the device 100 is adapted to store a device identifier enabling for uniquely identifying the device 100.
The control module 106 is adapted to be connected to the memory 108 for retrieving the device identifier to be included in the notification signal. The transmitter 110 is adapted to be connected to the control module 106 for transmitting the notification signal to a remote receiver 142. The transmitter 110 comprises a wireless electrical antenna (not showed) adapted to transmit the notification signal to the remote receiver 142. The battery 98 is adapted to be connected to the electronic components of the device 100 requiring power supply. In an embodiment of the invention, the battery 98 is connected to the memory 108, the transmitter 110 and the control module 106. In an embodiment of the invention, the battery 98, memory 108, transmitter 110, and control module 106 are printed in an integrated circuit.
In an embodiment of the invention, the tampering sensor 104 is a light sensor which is adapted to change state based on the quantity of light it is exposed to. The light sensor is adapted to be coupled to the blocker 102 such that amount of light to which the light sensor is exposed to would vary depending on the position of the blocker 102. The variation of light amount leads to a variation in the resistance of the light sensor. This variation in the resistance of the light sensor is detected by the control module 106 which, based on this information, determines whether the blocker 104 has moved from a blocking position to an unblocking position.
In another embodiment of the invention, the tampering sensor 104 is a piezoelectric sensor. The piezoelectric sensor is adapted to produce an electric signal output when mechanical stress acts upon the sensor. The piezoelectric sensor is adapted to be coupled to the blocker 102 in such a manner that, after being positioned in blocking position, any attempt to alter the position of the blocker 102 would lead to a mechanical stress being applied on the piezoelectric sensor which would result in a variation in the resistance of the sensor. This variation in the resistance of the sensor is detected by the control module 106 which, based on this information, determines whether the blocker 104 has moved from a blocking position to an unblocking position.
The piezoelectric sensor can be a bending piezoelectric sensor which changes resistance based on the bending degree of the sensor. The bending piezoelectric sensor 104 is coupled to the blocker 102 in such a manner that it takes a first bending degree when the blocker 102 is in a blocking position and a second bending degree when the blocker 102 is in an unblocking position. In an example, the blocker 102 can take the shape of a tag adapted to cover the sealing/closing element 102. In this case, the piezoelectric bending sensor 104 is coupled to the tag in a manner such that when the tag is used to cover the sealing/closing element 130, the tag has an extended/straight posture without any flexion and so does the piezoelectric bending sensor 104. The tag is adapted such that the only way to remove the tag from the sealing/closing element 140 (even partially) is through a flexion/bending action. This flexion/bending action of the tag results in the flexion/bending of the piezoelectric sensor 104 which results in a change of resistance of the sensor 104. This change of electrical properties is detected by the control module 106 which concludes to a tampering attempt of the blocker 104.
The control module 106 is adapted to detect the change of state of the tampering sensor 104 which corresponds in this case to the variation in the electrical state of the tampering sensor 104, which in turn is based on the variation in the position of the blocker 102. When a variation in the electrical state is detected, the control module 106 obtains the unique device identifier from the memory 108, generates a notification signal comprising the unique device identifier and transmits the notification signal to the transmitter 110 for transmission to the remote receiver 142. The transmitter 110 comprises a wireless electrical antenna (not shown) for transmitting the notification signal to the remote receiver 142.
The connector 112 is adapted to connect the blocker 102 to the sealing/closing element 130 of the object 140. The connector 112 can be the same physical component as the blocker 102 or a different component. The connector 112 is adapted to have a suitable structure in order to enable the blocker 102 to be positioned in a blocking position with respect to the sealing/closing element 130. In an embodiment of the invention, the connector 112 can also be adapted to connect the whole device 100 to the object 140 while serving its primary function of positioning the blocker 102 in a blocking position with respect to the sealing/closing element 130. The connector 112 can be in the form of an adhesive adapted to enable the blocker 102 to adhere to the sealing/closing element 130 with the aid of an adhesive material. The connector 112 can also have a mechanical structure such as a clip or a pin for example adapted to enable such a purpose.
In an embodiment of the invention, the device 100 can take the form of a user tag comprising the different components, knowing the battery 98, the memory 108, the transmitter 110, the control module 106, the tampering sensor 104, the blocker 102 and the connector 112. The components of the device 100 can be embedded within the user tag. The electronic components can be implemented using any suitable technology such an integrated circuit board. The tag (or at least a part thereof) is used as the blocker 102 to which the tampering sensor 104 is connected. This connection between the tag and the sensor 104 can be conducted using an adhesive material. The connector 112 is preferably an adhesive label (sticker) adapted for adhering the tag to the sealing/closing element 130. The part of the tag used as a blocker 102 and to which the tampering sensor 104 is connected is preferably made of a bendable material such as paper, rubber or plastic. The tag is preferably adapted to be in an extended position (without any flexion/bending) when it is adhered to the sealing/closing element 130 (blocking position) and to be flexed/bended when it is being removed (at least partially) from the sealing/closing element 130 (unblocking position).
The tampering sensor 104 is preferably a piezoelectric bending sensor in this case adapted to change resistance with the bending position of the tag. When the tag is being removed from the sealing/closing element 130, the piezoelectric bending sensor is forced into a bending position which results in a variation of its resistance. This variation of resistance is detecting by the control module 106 which interprets this action as an action/attempt to remove the blocker 104 from the sealing/closing element 130. The control module 106 obtains the device identifier from the memory 108 and generates a notification signal with an indication of the device identifier and the tampering action/attempt to the transmitter 110 which transmits the notification signal using its integrated antenna (not shown) to the remote receiver 142.
The tempering sensor 104 can alternatively be a light sensor. When the tag is adhered to the sealing/closing element 130 in a blocking position, the light sensor is hidden under the tag with no exposure to the light. When the tag is being removed from the sealing/closing element 130, this leads in exposing the light sensor at least partially to the light coming from the environment. This exposure to the light results in a variation of the sensor resistance which is detected by the control module 106 and interpreted as an action/attempt to remove the blocker (tag in this case) 102 from the sealing/closing element 130. The control module 106 therefore generates and sends a notification signal comprising the device identifier and an indication of the tampering action/attempt using through transmitter 110 to the remote receiver 142.
As illustrated in
The RFID transmitter 128 is adapted to generate and transmit an electrical signal comprising the TID to a remote RFID receiver 148 (see
The control module 106 and the tampering sensor 104 are adapted to be connected to the RFID tag device 120. The tampering sensor 104 is adapted to be connected to the blocker (tag) 122 such as any removal of the blocker (tag) 122 away from the sealing/closing element 130 would result in changing the state of the tampering sensor 104 from the first state to the second state which would in turn lead to a variation of the resistance of the sensor 104. The variation of the resistance in the sensor 104 is detected by the control module 106. The control module 106 is adapted to be connected to the RFID transmitter 128 for triggering the transmitter 128 for sending a notification signal if a tampering attempt is determined by the control module 106. The RFID transmitter 128 sends a signal to the remote RFID receiver 148 comprising the TID. The transmission of the signal is an indication of the tampering of the blocker 102.
As shown in
According to an embodiment of the invention, the tamper device 100 comprises a plurality of blockers 102a, 102b & 102c adapted to be used to block the plurality of sealing/closing elements 130a, 130b &130c. The plurality of blockers 102a, 102b & 102c can respectively be connected to a plurality of tampering sensors 104a, 104b & 104c. Depending on the mechanical form of the object 140 and the distance between the plurality of sealing/closing elements 130a, 130b & 130c, a single tampering sensor can be sufficient. If it is the case, a single tampering sensor 104a, 104b or 104c is connected to the plurality of the blockers 102a, 102b & 102c. This design option, when practically suitable, results in cost reduction in the manufacturing of the device 100. The plurality of blockers 102a, 102b & 102c can consist of a same physical unit or, alternatively, can be separate physical units.

When a notification signal is received by the reporting unit 144, the notification signal comprises a device identifier which is used by the reporting unit 144 to query the identifiers database 146.
As device identifiers are mapped to users' identification information inside the database 146, the reporting unit 144 receives back from the database 146 identification information of the user associated with the device having the queried device identifier. The reporting unit 144 generates and transmits an alarm signal comprising the user identification information. The alarm signal is indicative of the tampering action/attempt being conducted by the user identified using the database 146. In an embodiment of the invention, the reporting unit 144 is adapted to be connected to a display device for displaying information about the tampering attempt/action comprising the user identification information. The display device can be associated with a mobile device, a palmtop, a wireless tablet, a wired computing system or a TV screen for example. In another embodiment of the invention, the reporting unit 144 is adapted to be connected to an administrator (such as a security guard) mobile device for reporting thereto the tampering attempt/action along with the user identification information. A mobile application can be provided on the administrator mobile device for receiving and processing the messages received from the reporting unit 144. The processing comprises displaying the messages to the administrator through a user interface of the mobile device.
The coupling of the security device 100 to the object 140 is then checked at the security gate 204. The security gate 204 can be the same physical unit as the registration desk 202. A user in possession of an object 140 is checked at the security gate 204 to make sure that the object 140 is secured with the tamper device 100. Subsequent to the checking process, the user is allowed to enter the secured area 202. Users carrying unsecured objects 208A-208B are not allowed access inside the secured area 200.
