Abstract: Three-dimensional image data is generated. According to an example embodiment, three-dimensional depth information is estimated from a still image. A set of monocular images and their corresponding ground-truth depth maps are used to determine a relationship between monocular image features and the depth of image points. For different points in a particular image, the determined relationship is used together with local and global image features including monocular cues to determine relative depths of the points.

Abstract: The invention provides a method, a system, and a computer program product checking for human interaction dynamically to enable access to a resource in a computing environment. The method comprises collecting a plurality of objects. For each object, a plurality of properties is defined. A set of objects is selected from the plurality of collected objects. Thereafter, queries are generated based on the properties of the selected objects. Queries which have a non-unique or ambiguous response are removed. One of the remaining queries is randomly selected. The answer to the query, based on properties of the selected objects, is stored. The selected set of objects and the selected query are presented to the user who is trying to gain access to the resource. The user is enabled access to the resource if the response received from the user is validated against the stored answer of the selected query.

Abstract: Methods and systems for providing a voice-based digital signature service are disclosed. The method includes a first user sending a document to a second user for signature, and the first user also sending a PIN to the second user and to a voice verification authority. The second user sending, to the voice verification authority, a voice recording comprising the PIN along with consent of the second user to the PIN. The voice verification authority comparing the voice recording with a predefined voice sample of the second user, and the PIN received from the first user with the PIN received from the second user. The voice verification authority then sending a notification to a signing entity based on the comparison. The signing entity signing the PIN of the document with a private key associated with the second user and sends an acknowledgement to the first user and the second user.

Abstract: Methods, systems, products and devices are implemented for editing video image frames. According to one such method, image content is embedded into video. A selection input is received for a candidate location in a video frame of the video. The candidate location is traced in subsequent video frames of the video by approximating three-dimensional camera motion between two frames using a model that compensates for camera rotations, camera translations and zooming, and by optimizing the approximation using statistical modeling of three-dimensional camera motion between video frames. Image content is embedded in the candidate location in the subsequent video frames of the video based upon the tracking thereof.

Abstract: Techniques and tools are described which provide control access mechanisms for contents made available by a service provider to a user. The user, after a registration process, uses a mobile application on a mobile device to generate a one-time content key. The content key is input into a set-top box which validates the key and provides access to the protected content. The mobile application allows for password protection for the user, as well as a recharging ability when its one-time content keys are exhausted.

Abstract: A method and system for adaptive vulnerability scanning (AVS) of an application is provided. The adaptive vulnerability scanning of an application assists in identifying new vulnerabilities dynamically. The endpoints of an application are scanned using a predefined set of rules. Subsequently, one or more possible vulnerabilities are presented. The vulnerabilities are analyzed and predefined rules are modified. The steps of scanning the application and modification of rules are iteratively repeated till the adaptive vulnerability scanning capability is achieved. A neural network is used for training the adaptive vulnerability scanner. This neural network is made to learn some rules based on predefined set of rules while undergoing the training phase. At least one weight in neural networks is altered while imparting the self learning capability.
