摘要： A system and method are disclosed for controlling metadata associated with content on an electronic device that includes displaying interface screens for user entry of metadata control instructions, accepting user instructions, modifying metadata of applicable content, and associating the modified metadata with the applicable content. The system can export and/or store the applicable content along with modified metadata. The system can automatically modify metadata according to one or more profiles. Relevant profiles can be determined based on the export mechanism, destination or type of content. The system can add watermarks to indicate metadata modification. The system can display metadata for user modification. The content can include photos, videos or other content. The system can display metadata and geolocation indicators for each content item that indicate whether that item has associated metadata and geolocation information. The user can selectively modify metadata of selected content.

摘要： A computer implemented method for improving security of a server computer that is configured to deliver computer program instructions to a remote client computer, and comprising, using an intermediary computer that is topologically interposed between the server computer and the remote client computer is provided. The intermediary computer is configured to intercept a first set of source code instructions from the server computer. The intermediary computer identifies first party operations that include operations on objects and the objects themselves. The intermediary computer identifies a first set of operations within the first party operations that are configured to define values for one or more objects based on one or more constants. The intermediary computer then generates a second set of operations, where the second set of operations are configured to define same values for the one or more objects, when executed by a web browser on the client computer. The intermediary computer transforms the first party operations into transformed first party operations by substituting the first set of operations with the second set of operations. The intermediary computer generates a second set of source code instructions that are based on the first set of source code instructions and the transformed first party operations. The intermediary computer then sends the second set of source code instructions to the client computer.

摘要： The present disclosure provides a method for protecting a dex file from being decompiled in an Android system. The method comprises the following content: 1) loading a dex file into an inaccessible memory of an Android system; and 2) during execution, by performing reference execution, preventing the dex file from being found. In the method for protecting a dex file from be ing decompiled in an Android system in the present disclosure, a dex file is loaded into an inaccessible memory by means of a reference method, so that the dex file is prevented from being locally downloaded tor being copied and propagated; during execution, by means of reference execution, a decompiling person is prevented from finding the dex file so that the decompiling person cannot perform reverse engineering, thereby protecting an Android program from being decompiled.

摘要： An apparatus and method are described for implementing a trusted dynamic launch and trusted platform module (TPM) using a secure enclave. For example, a computer-implemented method according to one embodiment of the invention comprises: initializing a secure enclave in response to a first command, the secure enclave comprising a trusted software execution environment which prevents software executing outside the enclave from having access to software and data inside the enclave; and executing a trusted platform module (TPM) from within the secure enclave, the trusted platform module securely reading data from a set of platform control registers (PCR) in a processor or chipset component into a memory region allocated to the secure enclave.

摘要： Removing high level logic structure from a source program. Two or more source program fields are characterized by their respective value characteristics. A first field is mapped, with respect to the source program, to a second field having similar value characteristics as the first field. A target program is then created by replacing, in the source program, the first field with the second field and replacing each first field value with a corresponding second field value thereby preserving the value characteristics of the source program.
