The method comprises calculating a hash value of a new file created or received on a local computing device, transmitting the hash value to the central infrastructure, comparing the hash value with a previously determined hash value stored in a database on the central infrastructure to determine whether the file is new to the network and if the file is new to the network, checking the file content with a content identifying engine, installed and updated on the central infrastructure. Content attributes are determined for the files which allow to perform appropriate actions on the local computing devices according to policy rules.

A more efficient way of enabling scalability in terms of pixel value resolution is achieved by temporally predicting a first and a second representation of a video material separately to each other with the first representation being of a lower pixel value resolution than the second representation, with mapping the first prediction residual or a reconstructed version thereof from the first pixel value resolution to the second pixel value resolution dependent on the second prediction signal obtained from temporally predicting the second representation, and by coding a second prediction residual being of the second pixel value resolution as representing a deviation between a combination of the second and third prediction signals and the second representation.

Methods and systems for sharing white space with primary services and other emerging services are provided. Signal distribution within a specified location, such as a dwelling, is performed using a home gateway that identifies unused white space, reserves such white space spectrum, and delivers data to one or more devices at the respective location using the reserved spectrum. Signalling between the devices and the gateway is performed over a shared signalling channel, which enables the gateway to advise the devices from where and when to receive data. The gateway also uses a common spectrum reservation OFDM symbol to advise the neighbouring gateways of the local spectrum reservation.

A camera (17) mounted on a rear view minor housing (5) of a vehicle (1), which captures a plan view image of the ground on one side of the vehicle for display on an in-vehicle visual display unit (13) is calibrated to correct for offset of the camera (17) from an ideal position. During calibration an image of a reference point (34) on the vehicle (1) is captured as the mirror housing (5) is swiveled from a rest position to an operative position. The offset of the actual position of the image of the reference point in the captured image from its ideal position is computed, and a look-up table is prepared, which indicates the position at which pixels of subsequently captured image frames should be located to produce image frames with offset correction.

A method is provided for an escrow cryptosystem that is essentially overhead-free, does not require a cryptographic tamper-proof hardware implementation (i.e., can be done in software), is publicly verifiable, and cannot be used subliminally to enable a shadow public key system. A shadow public key system is an unescrowed public key system that is publicly displayed in a covert fashion. The keys generated by the method are auto-recoverable and auto-certifiable (abbrev. ARC). The ARC Cryptosystem is based on a key generation mechanism that outputs a public / private key pair, and a certificate of proof that the key is recoverable by the escrow authorities. Each generated public / private key pair can be verified efficiently to be escrowed properly by anyone. The verification procedure does not use the private key. Hence, the general public has an efficient way of making sure that any given individual's private key is escrowed properly, and the trusted authorities will be able to access the private key if needed. Since the verification can be performed by anyone, there is no need for a special trusted entity, known in the art as a "trusted third party". The proof and verification method involves one party proving to a second party that a third party can gain access to an encrypted value. In addition, the system is designed so that its internals can be made publicly scrutinizable (e.g., it can be distributed in source code form). This differs from many schemes which require that the escrowing device be tamper-proof hardware. The system is efficient and can be implemented as a "drop-in" replacement to an RSA or ElGamal cryptosystem. The system is applicable for lawenforcement, file systems, e-mail systems, certified e-mail systems, and any scenario in which public key cryptography can be employed and where private keys or information encrypted under public keys need to be recoverable. The system security relies solely on the security of cipher systems involved whose security has been extensively studied in the past.

The system is applicable for law-enforcement, file systems, e-mail systems, certified e-mail systems, and any scenario in which public key cryptography can be employed and where private keys or information encrypted under public keys need to be recoverable. Another aspect of the system is the possibility to organize it in a hierarchical tree structure, where each element in the tree is an escrow authority (or authorities) capable to recover keys and / or information encrypted under these keys within the subtree rooted at the authority (or authorities) and only within this subtree.

The ARC Cryptosystem is based on a key generation mechanism that outputs a public / private key pair, and a certificate of proof that the key was generated according to the algorithm.

Since the verification can be performed by anyone, there is no need for a special trusted entity, known in the art as a "trusted third party". The cryptosystem is overhead free since there is no additional protocol interaction between the user who generates his or her own key, and the certification authority or the escrow authorities, in comparison to what is required to submit the public key itself in regular certified public key systems. Furthermore, the system is designed so that its internals can be made publicly scrutinizable (e.g., it can be distributed in source code form). This differs from many schemes which require that the escrowing device be tamper-proof hardware.
