According to some embodiments, a method for embedding location information into a video comprises: separating the video into at least one key frame and at least one in-between frame set corresponding to the at least one key frame; receiving location data for the at least one key frame; encrypting the location data for the at least one key frame based on a location private key; and embedding the encrypted location data into the at least one key frame. ## Claims ### Claim at position 1 1-50. (Cancelled) ### Claim 51 An apparatus for embedding location information into a video, the apparatus comprising: at least one processor; and at least one memory including computer-executable code, wherein the at least one memory and the computer-executable code are configured to, with the at least one processor, cause the apparatus to: separate the video into at least one key frame and at least one in-between frame set corresponding to the at least one key frame; receive location data for the at least one key frame; encrypt the location data for the at least one key frame based on a location private key; and embed the encrypted location data into the at least one key frame. ### Claim 52 (depends on 51) The apparatus according to claim 51, wherein the computer-executable code are further configured to, when executed by the at least one processor, cause the apparatus to: embed the encrypted location data into each frame of the at least one in-between frame set. ### Claim 53 (depends on 51) The apparatus according to claim 51, wherein the computer-executable code are further configured to, when executed by the at least one processor, cause the apparatus to: detect a longest stroke from the at least one key frame; and embed the encrypted location data into the longest stroke. ### Claim 54 (depends on 52) The apparatus according to claim 52, wherein the computer-executable code are further configured to, when executed by the at least one processor, cause the apparatus to: detect a longest stroke from each frame of the at least one in-between frame set; and embed the encrypted location data into the longest stroke. ### Claim 55 An apparatus for extracting location information from a video, the apparatus comprising: at least one processor; and at least one memory including computer-executable code, wherein the at least one memory and the computer-executable code are configured to, with the at least one processor, cause the apparatus to: separate the video into at least one key frame and at least one in-between frame set corresponding to the at least one key frame; extract encrypted location data from the at least one key frame; and decrypt the encrypted location data based on a location public key. ### Claim 56 (depends on 55) The apparatus according to claim 55, wherein the computer-executable code are further configured to, when executed by the at least one processor, cause the apparatus to: detect a longest stroke from the at least one key frame; and extract the encrypted location data from the longest stroke. ### Claim 57 (depends on 55) The apparatus according to claim 55, wherein the computer-executable code are further configured to, when executed by the at least one processor, cause the apparatus to: in response to the encrypted location data being decrypted successfully, cause to play the video and show the decrypted location data. ### Claim 58 An apparatus for hiding at least first and second copyright watermark data into a video, the apparatus comprising: at least one processor; and at least one memory including computer-executable code, wherein the at least one memory and the computer-executable code are configured to, with the at least one processor, cause the apparatus to: separate the video into at least one key frame and at least one in-between frame set corresponding to the at least one key frame; and merge the at least first and second copyright watermark data into the at least one key frame. ### Claim 59 (depends on 58) The apparatus according to claim 58, wherein the computer-executable code are further configured to, when executed by the at least one processor, cause the apparatus to: merge the at least first and second copyright watermark data into each frame of the at least one in-between frame set. ### Claim 60 (depends on 58) The apparatus according to claim 58, wherein the computer-executable code are further configured to, when executed by the at least one processor, cause the apparatus to: store the at least first and second copyright watermark data in a stack structure or an array structure; and merge the stack structure or the array structure into the at least one key frame. ### Claim 61 (depends on 60) The apparatus according to claim 60, wherein the computer-executable code are further configured to, when executed by the at least one processor, cause the apparatus to: merge the stack structure or the array structure into each frame of the at least one in-between frame set. ### Claim 62 An apparatus for decoding a copyright watermark data from a video, the apparatus comprising: at least one processor; and at least one memory including computer-executable code, wherein the at least one memory and the computer-executable code are configured to, with the at least one processor, cause the apparatus to: separate the video into at least one key frame and at least one in-between frame set corresponding to the at least one key frame; read a data structure from the at least one key frame, the data structure having stored therein at least first and second copyright watermark data; and decode the first or second copyright watermark data according to a property of the data structure. ### Claim 63 (depends on 62) The apparatus according to claim 62, wherein the computer-executable code are further configured to, when executed by the at least one processor, cause the apparatus to: when the data structure is an array structure, decode the first or second copyright watermark data based on its corresponding private key; and when the data structure is a stack structure, decode the first watermark data based on the first private key, and decode the second watermark data based on the first and second private keys, wherein the first watermark data is located on top of the second watermark data in the stack structure.
