20090293116 | Accessing Protected Content In A Rights-Management Architecture - A digital rights management system for the distribution, protection and use of electronic content. The system includes a client architecture which receives content, where the content is preferably protected by encryption and may include a license and individualization features. Content is protected at several levels, including: no protection; source-sealed; individually-sealed (or “inscribed”); source-signed; and fully-individualized (or “owner exclusive”). The client also includes and/or receives components which permit the access and protection of the encrypted content, as well as components that allow content to be provided to the client in a form that is individualized for the client. In some cases, access to the content will be governed by a rights construct defined in the license bound to the content. The client components include an object which accesses encrypted content, an object that parses the license and enforces the rights in the license, an object which obtains protection software and data that is individualized for the client and/or the persona operating the client, and a script of instructions that provides individualization information to a distributor of content so that the content may be individualized for the client and/or its operating persona. Content is generally protected by encrypting it with a key and then sealing the key into the content in a way that binds it to the meta-data associated with the content. In some instances, the key may also be encrypted in such a way as to be accessible only by the use of individualized protection software installed on the client, thereby binding use of the content to a particular client or set of clients. | 11-26-2009 |
20110239005 | Secure Repository With Layers Of Tamper Resistance And System And Method For Providing Same - A secure repository individualized for a hardware environment and a method and system for providing the same. The secure repository includes a hidden cryptographic key and code that applies the key without requiring access to a copy of the key. The code that implements the secure repository is generated in a manner that is at least partly based on a hardware ID associated with the hardware environment in which the secure repository is to be installed, and may also be based on a random number. Cryptographic functions implemented by the secure repository include decryption of encrypted information and validation of cryptographically signed information. The secure repository may be coupled to an application program, which uses cryptographic services provided by the secure repository, by way of a decoupling interface that provides a common communication and authentication interface for diverse types of secure repositories. The decoupling interface may take the form of a single application programmer interface (API) usable with multiple dynamically linkable libraries. | 09-29-2011 |

The system includes a gaze attractor for attracting the gaze of the subject to cause an eye of the subject to move into alignment with regard to an interrogation signal source and/or response signal sensor to facilitate detection of a signal from the eye of the subject. | 06-12-2014 |
20140198297 | USING A 3D DISPLAY TO TRAIN A WEAK EYE - A method for treating a weak viewer-eye includes the steps of receiving eye-strength data indicative of an eye-strength of the weak viewer-eye and causing a 3D display system to vary, in accordance with the eye-strength of the weak viewer-eye, display characteristics of a perspective that the 3D display system displays. | 07-17-2014 |
20140200079 | SYSTEMS AND METHODS FOR DIFFERENTIATING BETWEEN DOMINANT AND WEAK EYES IN 3D DISPLAY TECHNOLOGY - A method of displaying visual information to different viewer-eyes includes receiving eye strength data indicative of a deficiency of a weak viewer-eye with respect to a dominant viewer-eye. The method further includes causing a 3D-display system to display a first perspective of an image to the weak viewer-eye and causing the 3D-display system to display a second perspective of the image to the dominant viewer-eye. A difference between the first perspective and the second perspective is a variation of a display characteristic of one of the first and second perspectives where the variation is made in accordance with the indicated deficiency of the weak viewer-eye | 07-17-2014 |
