Abstract: In one embodiment, a method of useful for generating a symmetric key includes the step of obtaining a sensor signal from a sensor of a mobile device. The method includes the step of determining one or more sampling points on said sensor signal. The method includes the step of extracting a sensor signal value at the sampling points. The method includes the step of generating the symmetric key from the sampled sensor signal value.

Abstract: In one aspect, in one aspect, a computerized method useful for reducing block boundary artifacts in a digital image processing that includes the step of obtaining an original digital image to scrambled. The method includes the step of generating a uniform grid of boxes in the digital image. At a boundary of each box in the uniform grid of boxes, a frame for each box is generated by replicating each of a set of boundary pixels a specified number of times to generate a thicker boundary. The method incudes the step of scrambling the uniform grid of boxes of the digital image.

Abstract: In one aspect, a computerized method for building a secondary index used to access index keys in a distributed database includes the step of providing a distributed database. The computerized method includes the step of providing a database file of the distributed database or on a cluster. The computerized method includes the step of building a first database index of index keys of the database file. The computerized method includes the step of organizing the first database index. The computerized method includes the step of, based on the organization of the first database index, building a second database index.

Abstract: In one aspect, a computerized method includes the step of obtaining an original digital image to scrambled. The computerized method includes the step of creating a copy of the digital image. The computerized method includes the step of delineating a first pixel-box grid on the digital image. The computerized method includes the step of delineate a second pixel-box grid on the copy of the digital image. The computerized method includes the step of joining the original digital image and the copy of the digital image. The he first pixel-box grid of the original digital image and of the second pixel-box grid are offset by a specified number of pixels; and scrambling the first pixel-box grid of the original digital image and of the second pixel-box grid of the copy of the digital image into an encoded digital image.

Abstract: In one embodiment, method of increasing security of computing-device mobile device communications comprising executing on one or more processors in a central repository server the step of obtaining a first user's public key. The first user's public key is one of a pair of certification keys generated by an application in a first user's computing device. The method includes the step of obtaining, from the first user via the first user's computing device, a set of first user's communication identifiers. The set of first user's communication identifier includes a first user's mobile device number, a first user's email address, or a first user's online social network identifier. The method includes the step of receiving a set of first user's communication identifiers from the first user via the first user's computing device. The method includes the step of generating one or more associations of the first user's public key with the set of first user's communication identifiers.

Abstract: A system for storing, restoring and distributing video-films, based on optical disks of very high definition, that makes use of DVD disks (Digital Versatile Disk) as a support for the storing of films, so that said films may be stored onto said disks in a compressed format according to the MPEG-2 standard, and where the algorithm allows to modify the compression factor according to the requested quality from a few Mbps to a considerable number of Mbps.

Abstract: A process of banner advertising display on an inquiring browser viewing a website over the Internet includes inquiring from the inquiring browser to a website authorizing display of banner advertising. Diversion from the website to an advertising system central controller occurs. The inquiring browser is supplied with code to enable sorting of a group of Internet ad addresses relative to the classification information related to the frequency of desired ad play. Sorting the Internet ad addresses relative to the classification information related to the frequency of desired ad play of each ad at the inquiring browser to form a sequential play list occurs at the browser. A process for accumulating the reports of ad play utilizing query strings is set forth in which the query strings are serially recorded, occasionally polled, and compiled into advertising system central controller in compatible reports.
