摘要： The disclosure features dendritic tags, and methods and systems for fabricating and using such tags. The methods can include obtaining at least one image of a dendritic tag attached to an article, analyzing the at least one image to identify a set of features associated with the dendritic tag, and comparing the set of features to stored information to identify the article.

摘要： Apparatus and methods for binding a wearable device for use with the wearable device, a terminal, and a server are presented. The method executed by the wearable device includes providing device information to the terminal, receiving a device certificate from the server, and storing the device certificate for performing payment using the corresponding user account. The method executed by the server includes receiving a binding request from the wearable device via the terminal, generating a device certificate of the wearable device based on the device identification, and providing the device certificate to the wearable device. The method executed by the payee device includes acquiring a transaction certificate of a wearable device and sending a payment collection request to a server including the transaction certificate of the wearable device and payment sum information.

摘要： The invention relates to a method for authenticating a user from a user terminal (UT), the method comprising: receiving by the user terminal, from a secure processor (ASRV, SE), a software component (GC) protected against tampering and reverse-engineering and configured to generate random pixels (PXi) having a probability lower than 100% to be visible in image frames; executing the software component by the user terminal, at a rate corresponding to a display refresh rate, to generate an image frame at the display refresh rate; displaying the generated image frames, which include machine unintelligible information (KYL, CC) formed of the random pixels, and becoming intelligible to a user at the display refresh rate; acquiring a response (POSi) from the user in relation with the information; transmitting by the user terminal the response to the secure processor, the user being authenticated when the response corresponds to the information and to a secret data (PC) shared by the user and the secure processor.

摘要： Methods, systems, and computer programs for generating cryptographic function parameters are described. In some examples, source code that defines seed information and a pseudorandom function is accessed. A parameter for a cryptographic function by operation of one or more data processors is generated. The parameter is generated from the seed information and the pseudorandom function. The parameter has a larger size in memory than the source code that defines the seed information and the pseudorandom function.

摘要： Sparse signal modulation schemes encode a data channel on a host image in a manner that is robust, flexible to achieve perceptual quality constraints, and provides improved data capacity. The host image is printed by any of a variety of means to apply the image, with sparse signal, to an object. After image capture of the object, a decoder processes the captured image to detect and extract data modulated into the sparse signal. The sparse signal may incorporate implicit or explicit synchronization components, which are either formed from the data signal or are complementary to it.
