System and method for bandwidth optimization in data transmission using a surveillance device

A method for protecting data security and optimizing bandwidth for data transmission, the method, comprising:

• computing a first set of checksum values for each of a first set of data blocks in a first data file;
• wherein, each of the first set of data blocks corresponds to non-overlapping data locations in the first data file;
• storing the first set of checksum values in a computer-readable storage medium;
• computing a second set of checksum values for each of a second set of data blocks in a second data file;
• wherein, each of second set of data blocks corresponds to non-overlapping data locations in the second data file that are same as the non-overlapping data locations in the first data file that correspond to the first set of data blocks;
• identifying updated blocks in the second set of data blocks;
• wherein, the updated blocks have different checksum values from corresponding blocks in the first set of data blocks having same data locations
• comparing checksum values of each of the updated blocks with one another;
• based on the comparison, identifying unique blocks from the updated blocks;
• and
• transmitting the unique blocks over a network.

A method for protecting data security and optimizing bandwidth in data transmission, the method, comprising:

• computing a checksum value of a data block;
• storing the checksum value of the data block in a computer readable storage medium;
• transmitting the data block to a remote server;
• computing an updated checksum value of an updated data block at a subsequent time;
• comparing the updated checksum value with the checksum value stored in the computer-readable storage medium;
• in response to determining that the updated checksum value is not equal to the checksum value, transmitting updated data block to the remote server.

A machine-readable medium having stored thereon a set of instructions which when executed perform a method of bandwidth optimization in live video streaming, the method, comprising:

• computing a current checksum value for a data block corresponding to a frame location in a current video frame;
• identifying a previous checksum value for a corresponding data block at a same frame location in a previous video frame as the frame location in the current video frame;
• comparing the current checksum value with the previous checksum value;
• in response to determining that the current checksum value is not identical to the previous checksum value, streaming the data block of the current video frame over a network.

A system for bandwidth optimization in live video streaming, the system, comprising:

• means for, computing a first set of checksum values for each of a first set of data blocks in a video frame;
• wherein, each of the first set of data blocks corresponds to non-overlapping pixel locations in the video frame;
• means for, storing the first set of checksum values in a computer-readable storage medium;
• means for, computing a second set of checksum values for each of a second set of data blocks in a subsequent video frame;
• wherein, each of second set of data blocks corresponds to non-overlapping pixel locations in the subsequent video frame that are same as the non-overlapping pixel locations in the video frame that correspond to the first set of data blocks;
• means for, identifying updated blocks in the second set of data blocks;
• wherein, the updated blocks have different checksum values from corresponding blocks in the first set of data blocks having same pixel locations
• means for, comparing checksum values of each of the updated blocks with one another;
• means for, identifying unique blocks from the updated blocks based on the comparison;
• and
• means for, transmitting the unique blocks over a network.
