An electronic watermark embedding apparatus according to an embodiment is an electronic watermark embedding apparatus capable of embedding an electronic watermark into a decoding circuit of secret-key encryption, and includes an embedding unit configured to generate the decoding circuit. The decoding circuit is embedded with the electronic watermark by being input with a common parameter generated in a setup of the secret-key encryption, a secret key of the secret-key encryption, and the electronic watermark, and is capable of decoding an encrypted text encrypted using the secret-key encryption.

Disclosed are a method for processing a dynamic image and an electronic device thereof. The method includes: taking a dynamic image and meantime recording a sound; extracting a sound print feature from recorded sound information; and writing an extracted sound print feature into the dynamic image, and performing sound print tagging on the dynamic image. According to the embodiments of the present disclosure, sound print tagging on the dynamic image is implemented, retrieving the dynamic image by category and quick match and query based on the sound print feature are implemented, which makes operations for users to retrieve an image more efficiently and intuitively.

Embodiments described include systems and methods for incorporating a watermark in an audio output. An embedded browser, which is executable on one or more processors of a client device, may detect an audio data stream from a network application accessed via the embedded browser. A watermarking engine of the embedded browser intercepts the audio data stream responsive to detecting the audio data stream. The watermarking engine incorporates a digital signal corresponding to a watermark into the audio data stream, prior to being produced as an audio output by an audio speaker. The watermarking engine causes the watermark to be present in the audio output produced by the audio speaker, the watermark configured to be inaudible by a human and recordable by an audio recording device.

An apparatus for reading out information from an information carrier includes a reading unit for reading out user information and access information from the information carrier. The user information are stored in a first region of the information carrier and the access information are stored in a second region of the information carrier. The apparatus further includes an access controller for providing access to the user information in dependence on the access information. The access information are stored in a first portion of the second region, and the dummy information are stored in a second portion of the second region according to a similar format as used for storing the access information.

An approach is provided for a segment-based viewing of a watermarked recording. The approach involves receiving a request, from an evaluator, to access one of a plurality of media associated with a plurality of interviewees, wherein each of the plurality of media represents a recording of an interview of a corresponding interviewee; and wherein the request relates to evaluation of the corresponding interviewee for admission or hiring. The approach also involves determining source-identifying information associated with the evaluator. The approach further involves determining source-identifying information associated with the request. The approach additionally involves generating a watermark based on the source-identifying information, wherein the watermark is configured to depict an identifier of the evaluator during a presentation of the requested media. The approach further involves modifying the one media to superimpose the watermark on the recording. The approach also involves initiating transmission of the requested media with the generated watermark to a target device associated with the evaluator.

An application platform configurable for collecting user data associated with a plurality of retail-branded credit cards is provided. The application platform includes a configurable front end comprising a graphical user Interface layer that is configurable to a specific one of the plurality of retail-branded credit cards, a backend layer comprising credit card functionality for directly performing credit card transactions associated with a specific one of the plurality of retail-branded credit cards, a data collection layer comprising a data collector for collecting user data associated with the plurality of retail-branded credit cards and an analytics engine coupled with the data collection layer for determining one or more attribute about a user from the user data associated with the plurality of retail-branded credit cards.

A method for execution by a customer premises receiver, comprising: receiving a signal that carries an original media stream; determining a location of the receiver; obtaining an identifier of an authorized region for the receiver; determining whether said location is contained within said authorized region; if said location is determined to be contained within said authorized region, outputting the original media stream for conveyance to a user; if said location is determined to not be contained within said authorized region, outputting a second media stream that is sufficiently corrupted relative to the original media stream as to degrade the user's viewing experience while being demonstrative of non-malfunctioning of the receiver. Also, a method, comprising a service provider releasing towards a plurality of customer premises receivers information regarding a respective geographic region within which each receiver is authorized to operate, wherein different geographic regions define coverage areas of different sizes.

Fingerprinting, including: receiving a plurality of master datasets, each master dataset divided into a plurality of input segments, wherein at least one master dataset of said plurality of master datasets is uniquely marked; selecting a corresponding input segment from one of said plurality of master datasets; storing a segment identifier indicating from which master dataset said selected corresponding input segment was selected; and sending said selected corresponding input segment to a client computer system over a computer network.
