Description
Technical field
The present invention relates to collectibles authentication techniques field, refer to especially a kind of encryption and authentication method and equipment of collecting the stages of digital video product.
Background technology
Digitized image (Digital Imaging), to take digital camera, electronic computer technology, digitlization memory technology and export technique to be basis, image file is carried out to data acquisition, arrange, take care of and make the overall process that becomes the true works that can touch, it comprises the implication of two aspects, that is: first is to be digitized as carrying and recording mode, and image is recorded and preserves; The secondth, by computer and the hardware device be associated thereof and graph and image processing software, digitized image file is modified, modified, and finally be converted into figure or the image file of digitlization storage.
Digitized image collection, be that the manufactured goods to digitized image with reserve value carry out autotelic collection, storage, classification, protection and appreciation, and then obtain the marginal benefit that comprises and be not limited to hold above-mentioned works and be worth.The same with the collection of other class, the digitized image collection should possess following characteristics equally: the rare property of material, irreplaceability, value preserving, appreciation, artistic appreciation, good keeping quality.
Collect digitalized image output, possess exactly making and export the needs that the client answers in the digitized image mechanism of high-end image qualification, take and meet collector collection needs and be basic goal, to digitized image carry out meticulous data acquisition, revise modification, color management, normalization management, safe storage be output as the overall process that can contact the goods in kind of touching with making.
Along with the present computer technology, the continuous progress of microelectric technique, the digitized image equipment develop rapidly of digital camera as representative take in drive, traditional image collection, keeping stores and manufacturing technology is numerous and confused stops production or biography type digitized image, have to admit, the image industry has not been that creep is not changed but undisputable fact by the traditional industrial transformation of chemistry as the basic mode of production towards total digitalization of take, wherein with the tap of U.S. tradition image industry---the bankruptcy protection of Kodak so that transition digital image, the company of Fuji of Japan marches digitized image comprehensively, it is the most representative that domestic Lekai company stops traditional business.Increasing photographic artist and shutterbugs select to create with digital camera, or traditional egative film are carried out to the laggard line number word output of digital scanning and make.
Meanwhile, the creation that develops into the photographic artist of digital image process software provides higher wide space, traditional darkroom technology progressively take the digitalized processing software of photoshop by representative and is being replaced, and day by day become the requisite authoring tools of photographer, become the part that making video output needn't be cut apart.
Transition and the progress of science and technology, be inconjunction with relevant image industry flourish, domestic preliminary shape to the foundational system of the assessment of Image Art product, criteria for classification, identification and analysis, and tentatively erect the operation channel of domestic Image Art product investment.
By follow-up study, the combing of being not difficult goes out the present situation of image investment.And can to this market, do further to divide according to different standards:
One, take the photography subject matter is standard, can be divided into the record, art and intention photography
Record photography refers to record the camera style that actual life is main demand, and material comes from real life, has the Humanistic Value of the major event of recording and historical Wen Xian.
Artistic photography refers to that take independently artistic expression is starting point, and it is the art creative activity of means that objective personage, things are carried out taking.
It is basic creation means that the intention photography refers to photograph, and coordinates digitlization figure image processing tool to carry out a kind of photography creation mode with the subjective thinking of visual communication or reproduction.
Relatively external collection experience, through implementation especially with the reflection historical event, or the record photographic work under specific environment and the representative artistic photography works of famous photographer are natural science level collection, all the other are many stowage mechanisms or individual's collection kind.
Two, take and take the shadow age and be standard, can be divided into older picture and contemporary photo
Older picture refers to that shooting time is the works before the 1980s, at the beginning of can dividing into the late Qing Dynasty the Republic of China, war, foundation, the Culture Revolution and Initial stages for reform and opening-up be the works of subject matter.
The present age photo refer to the reform and opening-up after so far every content subject matter and the works of expression way.
Current domestic image go out to be hidden great majority or comparatively main with the kind of older picture, the reflection particular historical particular persons in period, particular event.
Three, with the manufacture craft of picture, divide, can be divided into traditional handicraft and digital process
Traditional handicraft refers to that conventional film is carrier, and the shooting creation that the darkroom technology of take carries out as implementation can be divided into silver salt, albumen, wet version, silver version works according to process means is different with the performance medium.The technique relative complex, have relatively high expectations to photographer's operative skill.Because make efficiency is low, the not high and making amount less of rate of finished products, technical implementation way has the historiography meaning therefore concluded price is relatively high in addition.
Digital process refers to by digital technology, computer aided technique and high-quality inkjet technology, digitized image printing is made into to the method for photographic work by modern colour management application.2004, Epson U.S. started to promote UltraGiclee arts reproduction technique, and pioneering issue certificate with guarantee 80 years colour-fast.Metropolitan Museum of Art, New York City, USA and Boston art museum are also started selling the replica of UltraGiclee process output.The world-famous museums such as the Paris, FRA Louvre Palace Art Museum, London British Museum, USA New York big city odeum, Boston art museum, Pennsylvania art museum, Gu Genhan museum, New York, Los Angeles Contemporary Arts Museum have sells and collection Giclee works.Beijing's Imperial Palace museum, China National Library, refined prosperous colored printing Co., Ltd, Taibei Palace Museum have all entered into the Giclee field.In exhibition more than the 13400 width works of Pingyao International Photography, there are more than 3,000 width to come from " Giclee " technology of Epson, wherein are no lack of all kinds of outstanding award-winning work.Numerous ink-jet printer producers start to contend this market, wherein the highest with Epson, Canon and Hewlett-Packard's occupation rate of market.Digital process is understood grafting usually on strict color management and high-quality print media; with the antagonism time, for a long time if new, will never fade is main popularizing idea; by most of museums, picture youth and stowage mechanism, generally accepted at present, become the new selection of investment collection.
As previously mentioned, the image collection of China is progressively set up and develops, and its sign can be regarded as:
1, begun to take shape the collection troop of the loyal image of heat of museum, image specialty gallery or mechanism, favorites person three aspects, and number and class improve progressively.
2, beginning to take shape auction company, professional gallery is main body circulation transfer system.
3, some directly or indirectly occur with the cultural products market frequent activity that the image collection is associated.
4, the large quantities of independent photography people of collection level works as the creation purpose that sell of take have appearred.
5, a set of relatively complete image Value accounting system is tentatively established.
The image collection, its critical elements is the foundation of pricing system, namely with which type of measure of value, the works in creator's hand is carried out to the price identification with money-form, to determine its works, whether carrying value is preferably arranged, and the assignment value of higher expected.This individual system should comprise four basic key elements, that is: author, content, technique and quantity.
The author, i.e. the creator of image works, its reputation, influence power and historical role, or the expection of creation growth is the price of direct effect works, and proportional with above-mentioned factor.
Content, i.e. whether the content of image carrying itself has higher artistry, whether has reflected particular historical period, particular persons, particular event and creator's independence and has conformed to the artistic expression of sociology height.
Technique, refer to and make the method that image adopts, and substantially can be divided into two kinds of chemical technology and digital process.The factor that wherein affects the works price comprises: make necessary time, flow process, works medium, works specification etc.
Quantity, refer to through making to form can collect and can circulate on market and pass the works finished product quantity allowed.
In four fundamentals " technique " key element become pricing mechanism in the most outstanding difficult point.Therefore, need to, from digital process, inquire into the Valuation Standard of making, workflow, operation medium and the works specification of setting up a set of digitalization collection level image works.
