Description

System and method for providing messenger ringtone which provides hidden information using unique information {System and Method for service of messenger bell contents providing hidden information using watermark}

The present invention relates to a system and method for providing a messenger ringtone in which hidden information is provided using unique information. More particularly, the present invention relates to a messenger ringtone using a unique information to generate a messenger ringtone concealing information set by a user in a ringtone and to another user. The present invention relates to a messenger ringtone providing system and method in which hidden information is provided using unique information that enables the received user to view the information hidden in the messenger ringtone.

Recently, the information industry is growing rapidly and extensively, and various multimedia contents are digitized and digital multimedia information is spreading very quickly and easily due to the rapid development of high speed communication networks such as the Internet. In the digital world, the value of information is so great that it can be accessed in various forms with the development of ICT. The trend of digitization of multimedia is further accelerated by its convenience in production, editing, processing, transmission and storage, and digitalized materials can be easily copied and distributed by anyone. Therefore, various problems such as permission, compensation, and restriction necessary for using the user's information, copying and transmission, dissemination of information, and the rights of the institution or individual who owns the information arise. There was a need.

DRM (Digital Rights Management) technology is a technology that manages the user's usage rights to prevent illegal use of digital multimedia contents. It is a technology that makes contents available using the encryption key only. Technologies related to copyright protection, such as watermarking technology and digital object identifier (DOI), fall into this category of DRM technology.

The above-mentioned DRM technology can use the content only by a user who has the right to use the encryption by using the encryption. However, if the right user plays the content, the screen is captured by using a capture tool or in the case of audio, the analog playback output is performed. There is a problem that can not prevent the illegal use of the content when receiving the digital storage.

In order to solve this problem, there is a combination of fingerprinting technology with DRM technology. Fingerprinting technology is a kind of watermarking. If watermarking technology inserts the copyright information of the original owner into the content unobtrusively to human perception and uses it to verify and prove the rights of the content, fingerprinting is based on watermarking technology. It is a more intelligent and active copyright protection technology that can track and verify users who have illegally copied because it contains not only copyright information but also distributed user information. That is, the fingerprinting technique inserts in real time when the user inserts the content in real time, not at the server side, and has an advantage of providing a larger amount of information than the conventional watermarking technique. For example, by inserting user information in real time when the DRM fingerprinting technology is played on the user terminal, the user's information can be checked within the duplicated content even if illegal copying is performed, thereby tracking the illegal user. Make it possible.

DRM technology (eg watermark, fingerprinting) applied to the above information protection is required for the robustness of the insertion that can detect the inserted information properly for data processing such as compression, noise, format conversion, attack, etc. When inserted, the detection efficiency is increased in response to the robustness, but disadvantages such as inserting noise into the original data occur. On the contrary, in the case of weak insertion, there is a problem that the detection efficiency is lowered while the advantage of being unobtrusive to human perception is coexisted. Therefore, in most cases, the robustness is set so that the inserted information can withstand only the data change that does not degrade the content itself against various data transformations, distortions, and attacks. This is because, in terms of ownership protection, it is deemed to be protected if the content is above a certain level of image quality or sound quality, and if the data damage due to noise or attack is more than a degree, the protection of the rights of the content is not considered. Because. In addition, since watermarking and fingerprinting have been developed mainly in PC-based environments, sufficient resources (eg, memory, processor) can be utilized in some degree of complexity or performance. However, when the resource environment is poor compared to the performance of the PC, such as a mobile communication terminal, it is very difficult to apply the conventional watermark and fingerprinting technology as it is. In addition, the inherent storage method and storage format of the mobile communication terminal have a lower quality of data than a general audio format. Recently, DRM technology has been studied to be used not only in terms of copyright protection but also in various aspects.

The process of inserting the unique information into the digital MIDI sound source which is the ringtone sound source to generate the messenger ringtone in the messenger ringtone generating means 14 according to the present invention is as follows. The delta time between each event of the digital MIDI sound source is adjusted to insert and detect one bit per event. A typical digital MIDI sound source consists of about 500 events. Therefore, even if the 8-byte audio watermark is repeatedly inserted, there is no big problem in sound quality. In this case, the delta time adjusted to insert unique information into the digital MIDI sound source is preferably adjusted to an ideal value that does not cause an abnormal sound quality even if the audio watermark is inserted through experiments. More specifically, each event and parameter value are read and the duration value of each event is read by parsing an event included in the digital MIDI sound source. Change the audio watermark by inserting it into the read duration value. At this time, the audio watermark is repeatedly inserted in the duration of each event bit by bit. The changed duration value is changed to the time apart from the initial start time and the end time is recorded. When all changed events are saved in a file in sequence, a digital MIDI sound source with a watermark is created. According to the above-described method, the messenger ringtone according to the present invention is generated by storing the audio watermark inserted in the digital MIDI sound source.

The above-described scheme is a case where the digital MIDI sound source is employed as the ringtone sound source used to generate the messenger ringtone, and the present invention is not limited thereto. It is apparent that various ringtone sound sources may be employed. In addition, the method of inserting the unique information into the ringtone sound source may be any method as long as it maintains the transparency and robustness of the unique information inserted into the ringtone sound source. Here, transparency refers to a characteristic that can easily recognize and extract the unique information inserted from the original ringtone sound source, and robustness refers to a characteristic that the inserted unique information can be protected even if any modification is applied to the ringtone sound source.

The messenger ring tone generated by the messenger ringtone generator 10 described above is transferred to the messenger ringtone transmitter 20 and transmitted to the first terminal 41 designated by the user.
