The present invention includes a light communication method and system wherein messages are transmitted via color code flashes. The light communication includes mechanisms for oversampling the color code flashes to enhance the accuracy of the method and system.

Various embodiments are generally directed an apparatus and method for processing an encrypted graphic with a decryption key associated with a depth order policy including a depth position of a display scene, generating a graphic from the encrypted graphic when the encrypted graphic is successfully decrypted using the decryption key and assigning the graphic to a plane at the depth position of the display scene when the encrypted graphic is successfully decrypted.

An optical security method for object authentication using photon-counting encryption implemented with phase encoded QR codes. By combining the full phase double-random-phase encryption with photon-counting imaging method and applying an iterative Huffman coding technique, encryption and compression of an image containing primary information about the object is achieved. This data can then be stored inside of an optically phase-encoded QR code for robust read out, decryption, and authentication. The optically encoded QR code is verified by examining the speckle signature of the optical masks using statistical analysis.

A system for controlling access to secured resources using a security token having a hologram embossed thereon is provided. A key is split into a user key and a complimentary key based on a mask, wherein key values in the user key correspond to idle state values in the complimentary key and vice versa. The user key is used to generate a user key array, that is used to generate a three-dimensional virtual image that is holographically embossed onto a security token. The hologram is merged with a corresponding hologram for the complimentary key and the combination compared to an image of an ensemble of the key. The combination can be mergers of images or extractions of holograms. If a match is found, within a tolerance, an access grant signal is sent to the secure resources, thereby securing the resources based on presence of the security token.

A system and method for pairing a mobile device with a computer for password-less login using a network service is provided. The method may include sending a pairing request to a network server from a computing device, wherein the pairing request includes computer authentication data and a computer public key. The network server may pair the mobile device with the computing device; wherein, the computing device may generate a pairing secret key and an associated QR image, which the user is prompted to scan using the mobile device. A pairing agent within the mobile device may validate the computer authentication data and parse the computer public key therefrom. In some embodiments a PIN could be displayed by the computer and entered by the user into the mobile device or silently exchanged between the computer and the mobile device, when proximate to each other, for the mutual authentication data validation. The method may further include registering the user mobile and computer devices for administrative management at the network server for an enterprise deployment or end user self-service management.

Security guards at big facilities, such as airports, monitor multiple screens that display images from individual surveillance cameras dispersed throughout the facility. If a guard zooms with a particular camera, he will lose image resolution, along with perspective on the surrounding area. Embodiments of the inventive Imaging System for Immersive Surveillance (ISIS) solve these problems by combining multiple cameras in one device. When properly mounted, example ISIS systems offer 360-degree, 100-megapixel views on a single screen. (Other resolutions may also be employed.) Image-stitching software merges multiple video feeds into one scene. The system also allows operators to tag and follow targets, and can monitor restricted areas and sound an alert when intruders breach them.

The disclosed computer-implemented method for image-based encryption of cloud data may include (1) identifying a user account for a cloud data store, wherein the cloud data store stores at least one secret to be secured by encryption on behalf of the user account, (2) receiving an image file to be used at least in part to generate a cryptographic element to be used for encrypting the secret, the cryptographic element capable of being re-created when the image file is provided again at a later time, (3) using at least one cryptographic function, generating the cryptographic element based at least in part on the image file, and (4) securing the secret by encrypting the secret using the cryptographic element. Various other methods, systems, and computer-readable media are also disclosed.

The invention provides an easy to use credential management mechanism for multi-factor out-of-band multi-channel authentication process to protect user access to online portals. When opened, the client processing application generates a multi-dimensional code. The user scans the multi-dimensional code and validates the client processing application and triggers an out-of-band outbound mechanism. The portable mobile device invokes the authentication server to get authenticated. The authentication server authenticates the user based on shared secret key and is automatically allowed access to the online portal. The process of the invention includes an authentication server, a client processing application to generate an authentication vehicle or an embodiment (i.e. multi-dimensional bar code) and handle incoming requests, secret keys and a portable communication device with a smartphone application.
