H04L 9/32

US Classification:

380201, 713189, 713193, 726 2

Abstract:

A system and method for securing intellectual property rights in distributed intellectual property. The present invention grants and polices rights in electronically distributed intellectual property. Use limitations are established by agreement by the content provider and the client. The use limitations are reflected in time-based, usage-based and player based component codes that are used to determine if the client is entitled to use the intellectual property. The present invention further protects the intellectual property from unauthorized use by encrypting the intellectual property with a key created from some or all of the component codes. As the component codes are known to both the client and the content provider, no key exchange is required by the present invention.

Appl. No.:

13/346291

Inventors:

David Weinstein - Laurel MD, US
Scott Lewis Dyer - Bedford MA, US

Assignee:

The MITRE Corporation - McLean VA

International Classification:

H04L 9/32
G06F 3/00

US Classification:

713168

Abstract:

A Secure Remote Peripheral Encryption Tunnel (SeRPEnT) can be implemented in a portable embedded device for the Universal Serial Bus (USB) with a much more restricted attack surface than a general purpose client computer. The SeRPEnT device can comprise a small, low-power “cryptographic switchboard” that can operate in a trusted path mode and a pass-through mode. In the trusted path mode, the SeRPEnT device can tunnel connected peripherals through the client to a server with Virtual Machine (VM)-hosted applications. In the pass-through mode, the SeRPEnT device can pass-through the connected peripherals to the client system, allowing normal use of the local system by the user. SeRPEnT can also enable secure transactions between the user and server applications by only allowing input to the VMs to originate from the SeRPEnT device.

Abstract:

A method for securing intellectual property includes establishing contact between an IP server and a client. At least two component codes are shared and pre-stored in both the player and the server prior to ordering the intellectual property. The IP server accepts an order for an intellectual property product from the client. The IP server creates a shared private key based on the pre-stored shared component codes and an additional shared component code at the time the intellectual property product is ordered. The shared private key is not distributed to the player software. The IP server encrypts the intellectual property product with the created shared private key prior to distribution to the client. The intellectual property product further comprises content data and rights data in digital form. The IP server electronically distributes the intellectual property product to the client in encrypted form without the shared private key.

International Classification:

G06F 21/00

US Classification:

726 25

Abstract:

A mobile device charging station configured to analyze, measure and respond to/correct the state of a mobile device. The charging station can employ an embedded cryptographic subsystem that can make use of anti-tamper/tamper evident techniques to protect stored firmware images/cryptographic material.

Assignee:

Pegasus Media Security, LLC - Reston VA

International Classification:

G06F 21/10
H04L 9/08
H04L 29/06

Abstract:

In some embodiments, a method includes sending an authentication request to a client device to obtain a utilization code in response to a request from the client device to access data. The utilization code is uniquely associated with the client device. The method includes obtaining an authentication response including the utilization code from the client device and authenticating the client device if the utilization code matches a utilization identifier stored in a database. The method includes generating an encryption key using a seed based at least in part on the utilization code and encrypting the data with the encryption key to generate encrypted data and sending, when the utilization code matches the utilization identifier stored in the database, the encrypted data to the client device without requiring a user of the client device to login.

Assignee:

Pegasus Media Security, LLC - Reston VA

International Classification:

H04N 5/913
H04N 9/806

Abstract:

In some embodiments, a method includes receiving, at a device, digital audio content to be converted by a digital-to-analog converter to produce analog audio content. The digital audio content has at least one audible frequency. The method also includes selecting, at the device, a first signal and a second signal to output with the analog audio content. The first signal has an inaudible carrier frequency and a bandwidth, and the second signal also has an inaudible carrier frequency and a bandwidth. A difference between the first signal and the second signal is an undesired audible signal. The method further includes outputting, from the device, the analog audio content, the first signal and the second signal, such that when the analog audio content is detected by a recording device the undesired audible signal is detected with the analog audio content.

International Classification:

G06F 21/10
G06F 21/62

Abstract:

A method detects unauthorized access of data, and includes receiving data from a content provider by a content reproducing device; storing the received data in a memory storage device of the content reproducing device; obtaining an address range of a buffer of the content reproducing device; intercepting system application programming interface calls related to memory access of the address range of the buffer; comparing the intercepted system application programming interface calls to an expected sequence of memory access calls; and determining that a particular memory access call is unauthorized when the particular memory access call accesses the address range of the buffer while not belonging to the expected sequence of memory access calls.
