Abstract
The invention relates to a portable storage device with a digital watermarking function, such as an SD card. The device can identify data written into the device, such as photos; if the data do not have a digital watermark, when the digital watermark is allowed to be added, the device automatically reads mark information pre-stored in the device, generates and automatically adds the digital watermark to the received data and then stores the data into a memory unit, so when read from the device at the next time, the data have the digital watermark. The device may have a built-in global positioning system (GPS) or acquire identical data interfaces to add positions and system time in the watermark. The portable storage device with the digital watermarking function can make all portable digital devices such as digital cameras, digital videos and cell phones automatically generate the digital watermark during photographing, so copyright information of an owner is marked and copyright disputes can be conveniently solved.
Description
Technical field
The present invention relates to a kind of can for the data file that writes add automatically digital watermarking the portable storage device controller and or portable storage device, belong to the digital copyright technology field.
Background technology
Portable storage device, general reference employing semiconductor fast-flash memory device (Flash) or satellite hard disk are as the various memory storages that can carry of memory device, different according to interface with outward appearance, comprising: SD card, MiniSD card, MicroSD card, mmc card, USB flash disk, portable hard drive etc.Be widely used in various portable electronic devices at present,, be mainly used in the storage of picture, music, data as digital camera, Digital Video, mobile phone etc.Especially in various digital cameras, SD is present common memory storage.
Digital watermarking (Digital Watermarking) technology is that some identification informations (being digital watermarking) are directly embedded in the middle of the digital carrier (comprising multimedia, document, software etc.), but do not influence the use value of original vector, be not easy to be perceiveed by people's consciousness system (as vision or auditory system) or notice yet.Be hidden in information in the carrier by these, can reach and confirm creator of content, buyer, transmission secret information or judge whether carrier purpose such as is distorted.At present, digital watermark technology mainly one of is used, and is the copyright information that is used to identify picture, and picture copyright holder's information is embedded in the middle of the picture by digital watermark technology, like this, in picture is used, can help solving dispute over copyright.At present, to be used for the picture copyright by copyright management units such as Beijing Copyright Bureau settled really for digital watermark technology.
But traditional digital watermarking need be in copyright registration etc., adds on the picture afterwards, and operation is convenient inadequately.Traditional solution is the digital camera of development support digital watermarking, when licence plate, just digital watermarking is added in the middle of the picture shot so at once.But special-purpose digital watermarking camera is not easy to popularize.
Thus; design a kind of digital watermarking algorithm storage controller that has; then exploitation can be added the portable storage device of digital watermarking automatically for the digital photo that deposits in; as the SD card; can directly be inserted in the digital camera; when camera is delivered to storing apparatus with picture shot; automatically recognition image; add digital watermarking; and then storage, picture has just added digital watermarking by when memory storage is read like this; can promote the popularization of digital watermark technology and copyright protection work greatly, promote the development of cultural industry.
Summary of the invention
The object of the present invention is to provide a kind of portable storage device, can the possessory information of believable storage, data layout and digital watermark information that identification receives, to the information that do not have digital watermarking add automatically the owner information that comprises storage inside and or the digital watermarking of content such as temporal information, be stored in the middle of the memory device then.Above-mentioned functions can be an individual components in memory storage, by data exchange interface and Memory Controller swap data at a high speed, also can be the function that Memory Controller itself possesses.
A kind of portable storage device that the digital watermarking function is arranged is characterized in that:
A1: have general external data Fabric Interface, a built-in controller MCU with data identification and digital watermarking inspection and calculation function or one group are realized the control device that the chip of above-mentioned functions is formed, and read-write interface that can the control store device.
A2: this device external data Fabric Interface can be SD, MiniSD, MicroSD, MMC, USB and the wired or wireless data exchange interface that can play said function.
A3: the data of reception can be discerned and check to this device, can when allowing to add digital watermarking, add digital watermarking automatically for the data that do not have data watermark, stores into then in the middle of the memory device;
A4: this device digital watermarking arithmetic element can be the part of controller, also can be one or one group of device, is connected with controller by internal bus.
A5: this device should have built-in believable internal storage unit, and storage is used for the flag information of digital watermarking.This flag information should be able to be write or be rewritten by the maker or the supvr of digital watermarking standard by the method for safety.
A6: this device is selected by accepting modes such as instruction or external switch, and enabling or forbidding of watermark function added in control;
A7: this device can also be selected the interface of unit such as built-in GPS or receiving position and temporal information, when adding digital watermarking automatically with till above-mentioned and temporal information add in the middle of the digital watermarking.
System architecture diagram as shown in Figure 1.
The present invention is applicable to various portable digital devices, adds digital watermarking for its various information that obtain from the outside, generates the data that have digital watermarking, is used for copyright protection etc.
Characteristics of the present invention and advantage are as follows:
This device can not transformed or change under the prerequisite of portable electronic equipments such as digital camera, adds digital watermarking automatically by the record data that use this device to generate as portable electronic equipments such as digital cameras automatically, identifies possessory copyright information.
Description of drawings
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is the theory structure block diagram of a kind of digital watermarking portable storage device of expression this patent, has shown the more prerequisite functional modules of this device.Said modules can be an one chip that comprises all component, also can be a core assembly sheet, and wherein the GPS assembly is optional assembly.
Embodiment
External data interface receives outside instruction or data, MCU cooperative digital watermark parts are checked data, if data do not have digital watermarking, then read digital watermarking flag information generation digital watermark data and add in the middle of the reception numeral, will have the data storage of digital watermarking then in the middle of memory period.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
