Abstract: Provided is a computer-implemented video processing method. The method comprises receiving a stream of original images related to a video access event and creating a stream of output images corresponding to the original images. The output images include first images comprising a hidden digital forensic marker and second images comprising a visible digital forensic marker. The hidden marker and the visible marker each encode information related to the video access event. The stream of output images is output onto a network or caused to be displayed on a screen. The visible marker serves as a deterrent for distribution or recording, and if an attempt is made to remove it, the hidden marker remains in the image, allowing the information relevant to the video access event to be recovered. Also provided are a method of integrity detection for a stream of images containing markers, and a method of embedding a dynamic marker.

Abstract: Method and apparatus for carrying out the method receiving packets, each of the packets comprising a header and a payload. For a particular packet among the packets, the method includes processing at least the header of the particular packet to determine a flow associated with the particular packet; attempting to determine a payload structure based on the flow, the payload structure associated with transport of coded video data in the payload of the particular packet; and if the attempting is successful, repackaging coded video data contained in the payload of the particular packet into a new packet and forwarding the new packet to an external system or storing the new packet in memory.

Abstract: Systems and methods are disclosed for locating a retroreflective object in a digital image and/or identifying a feature of the retroreflective object in the digital image. In certain environmental conditions, e.g. on a sunny day, or when the retroreflective material is damaged or soiled, it may be more challenging to locate the retroreflective object in the digital image and/or to identify a feature of the object in the digital image. The systems and methods disclosed herein may be particularly suited for object location and/or feature identification in situations in which there is a strong source of ambient light (e.g. on a sunny day) and/or when the retroreflective material on the object is damaged or soiled.

Abstract: Technologies exist that allow for power to be supplied over a data connection, e.g., Power over Ethernet (PoE). Power sourcing equipment (PSE) supplies power to a powered device (PD) over the data connection. There may be applications in which it is desired or necessary to insert an intermediary device on a data connection between the PSE and the PD. An intermediary device is disclosed that can be inserted between a PSE and a PD. The intermediary device attempts to power itself using power supplied by the PSE over the data connection, rather than using an auxiliary power supply. In some embodiments, the intermediary device acts like a PD and requests from the PSE enough power for both itself and the actual PD. The intermediary device then also acts as a PSE to deliver unused power over the data connection to the actual PD.

Abstract: Technology permitting secure storage and transmission of data stream as well as tiered access to multiple data stream according to permission. Data streams may be encrypted using symmetric encryption performed with varying symmetric keys according to a key stream of symmetric keys. Native data may be discarded for safety. Whole or partial key streams may be encrypted using the public keys of authorized entities having permission to access respective data streams or portions thereof. Only the corresponding private keys can decrypt the encrypted key streams required to decrypt the encrypted data streams. Thus rigorous access control is provided. IT personnel accessing data stream files on a server or intruders maliciously obtaining files will not be able to derive the data stream. Sensitive data streams may be stored using cloud services despite inherent risks.

Abstract: An access controller combines one or more Secure Access Modules (SAMs) or other cryptographic processors with embedded storage, individually accessible by the controller such that waiting on the reply from one of the modules does not prevent accessing the others, a host CPU, running the computer program to perform authentication and access control, and a waiting queue, possibly in system memory, to put the request in when all SAMs are used. The state of the SAMs, possibly using system memory, is tracked to be able to find a free access module or to be able to match a response to the corresponding request. One or more connections (serial, network, wireless or otherwise) are used to connect to transparent smart card readers and door controllers.
