A method of unambiguous identification and authentication of products for the purpose of better recognition of product forgeries and controlling product piracy, including applying to/into the product an identification substance admixture which contains paramagnetic phases or identifying a product which contains an identification substance admixture containing paramagnetic phases and has an ESR fingerprint spectrum that permits unambiguous identification of the product. Such an ESR fingerprint spectrum is easily measurable, but can be copied or forged only with difficulty. The method relates to an individualizable “femto tag” for femto ledgers and forms an important interface for what are known as “Internet of Things” (IOT).

Methods and systems for verifying authenticity of a physical object and/or for verifying possession of the object by an individual are described. In one embodiment, the object is registered with a remote processing system. Data representing at least one characteristic of the object is obtained and stored in the remote system and the identity of the individual or entity possessing the object is authenticated. After authenticating the individual, an identifier is collocated (or an existing mechanism is activated or modified to replicate the identifier) with the object, where the identifier uniquely identifies the object and the individual possessing the object. The object and the identity of the individual possessing the object can be authenticated at a future time by sensing the collocated identifier and sending the sensed identifier to the remote system. The remote system can send instructions to an entity wishing to authenticate the object and its association with the individual possessing the object. The instructions can be set up at the time the object is registered in the remote system. The remote system can perform an interactive or automated session with the entity wishing to authenticate the object, thereby saving time and providing a robust method of authentication and means for carrying out additional processing functions.

Disclosed is a process of adding PUF materials with non-repeatable random order to the additive manufacturing process of a product. Preferably, these materials have magnetic characteristics. These characteristics can be detected by a sensor which reads the random pattern and provides a unique signature for the item produced.

A magnetoresistive magnetic imaging sensor for identifying a magnetic image comprises a PCB and several magnetoresistive sensor chips, wherein the several magnetoresistive sensor chips are located on the PCB, and the PCB is perpendicular or parallel to the magnetic image detection surface. It has a lateral detection mode and front detection mode. In the lateral detection mode, each side face of the several magnetoresistive sensor chips is parallel or coplanar with the side of the PCB, and parallel to the magnetic image detection surface. The several magnetoresistive sensor chips have the same magnetic sensing direction. In the lateral detection mode, the adjacent magnetoresistive sensor chips are stacked, while in the front detection mode, the adjacent magnetoresistive sensor chips are arranged in a staggered manner, in order to achieve continuity of the detection area in the magnetic image detection surface. The magnetoresistive magnetic imaging sensor may also comprise a permanent magnet assembly and a housing. The sensor has several advantages, including continuity across the detection area, good signal reproduction, high sensitivity, and low power consumption.

A system for evaluating a stream of sensor data formed by means of at least one sensor for a plurality of value documents includes at least two evaluation units and a data bus. Each of the evaluation units has first and second interfaces for receiving or transferring the sensor data stream with the sensor data, a third interface for receiving and transferring evaluation data, a working memory, at least one processor connected to the working memory for evaluating the sensor data in the working memory, and a relaying device connected to the first and the second interfaces and to the working memory for receiving a sensor data stream received via the first interface, at least partial relaying to the second interface and to storage of at least part of the data of the sensor data stream in the working memory, with the data bus being connected to the third interface.

Disclosed are a sampling method for anti-counterfeiting information about a cash note, and a sampling apparatus for anti-counterfeiting information about a cash note, which executes the method. The sampling method for anti-counterfeiting information about a cash note comprises: through differences collected between sensors, utilizing a law of the differences to restore spatially coupled power-frequency of low-frequency electromagnetic interference signals acquired by an effective signal sensor (21); and then performing common-mode signal elimination on voltage waveform data corresponding to the anti-counterfeiting information, thereby thoroughly elimination the spatially coupled power-frequency or low-frequency electromagnetic interferences that magnetic signal sensors suffer from during the collection of magnetic anti-counterfeiting signals.
