Description
Technical field
The present invention relates to a kind of portable equipment, beaten especially with respect to a kind of virtual printing and the portable emulation of encrypting carrying
Printing equipment is put.
Background technology
With the development of science and technology, many early stages can not gradually have been catered to, completely using the information of hard copy as main transmission medium
The current demand of foot, except it is excessive in information content and the problem of substantial amounts of paper must be used in addition to, still having many information to be can not
Effect to be presented is presented using hard copy and needs special reading device suitably to show, and is such as maintained secrecy in the presence of other
The problem of property etc..By taking medical information as an example, medical information has turned into medical institutes and necessary one of people's daily life
Point, and the foundation that the data of medical diagnosis judge as doctor is particularly important, such as report of medical image, physiological examination, case history
It is the Primary Reference foundation of diagnosis sufferer disease.However, current medical image, report or case history etc. information are main still
It is that, mainly to transmit medium, it is not only inefficent and expends a large amount of precious resources, has quite to environmental protection using the paper of printing
Big injury.
Although current others electronic medias（Such as CD）It is very universal, but can not be extended to and have as foregoing
The information transmission of personal information privacy's property demand, its be mainly due to ensure the protections of those medium transmission informations with
Completely and cause cost and environmental injury problem.For example, although CD of new generation can store diversity, it is a large amount of
Information, and can further improve the accuracy of diagnosis, but CD generally has the problem of preservation is difficult, and on CD information
Protection is difficult and is difficult to repeat or updates read-write, also Chang Yinwei its cause more environmental problems using substantial amounts of plastic raw materials
And be that This is what people generally disapprove of.In addition, Portable disk is perhaps to environment friendly product relatively, but utilize general Portable disk transmission information
Still have the doubts of many, such as easily poisoning, Information Security defence is not enough, be easily modified and software and hardware compatibility not
Good the problems such as.
Find simpler, more convenient, the more environmentally friendly and mobile storage mode that can reuse reduces medical treatment consumptive materials and used
Amount, reduces pollution discarded object, it is to avoid the demand such as chemical contamination, ink, CD consumptive material, film consumptive material, so as to reduce many patients
Inspection burden and Hospital operation cost, while reducing environmental pollution, this is always one of content that applicant endeavours research.
The content of the invention
For solve that the information transmission technique of current main flow causes pollute, inconvenience, the technical problem such as information security, it is of the invention
Propose in the way of virtual printer, the important information to be transmitted is allowed in the form of it can not change and possess information privacy, with void
Intend printing type and be stored in Portable disk, so as to reaching complete file, be easy to carry and uniform format portable memory device, solution
The problems of certainly existing technology.
The present invention proposes a kind of portable virtual printer, and it is electric with the master controller comprising a master controller and respectively
Property connection one can a heat insertion coffret and storage element, the master controller includes an embedded firmware, in it storage can with it is outer
One printing of one computer communication in portion and conversion program and a virtual printer driver, the virtual printer driver
Foundation and the information transmission agreement of the outside computer, the master controller hot can insert coffret through this and receive the computer
The print command of output, and perform the printing and conversion program the print command is converted into an output mimeograph documents and is stored in
The storage element.
Wherein, the printing and conversion program include a cryptographic means, and it is the output mimeograph documents after conversion to be given
To be stored in the storage element after encryption.
Wherein, the cryptographic means can be password encryption or the encryption of public and private key, and computing is encrypted according to a private key in it, leads to
Cross encryption key to compare to determine corresponding authority to the data access in output mimeograph documents, the private key is as in cryptographic calculation
Primary encryption numerical value.
Wherein, a public key of the cryptographic means, the private key are stored the embedded firmware and the storage by the master controller respectively
In memory cell in a specific memory region.
Wherein, it is hiding to store the memory region of the private key.
Wherein, it is USB, SATA, FireWire or a Thunderbolt that this, which hot can insert coffret,.
Wherein, the storage element is flash memory (such as NAND Flash), solid state hard disc or micro hard disk.
Wherein, storage element NAND flash memories, it includes multiple different memory regions, wherein including last
The memory region of individual logic unit is appointed as hiding and/or encrypting for the storing memory private key.
Wherein, the output mimeograph documents are not editable file format.

The information such as the print command of calculation machine 50, and produce output mimeograph documents be stored in the storage element 30.
Further, the program that storage can open the output mimeograph documents in the storage element 30 is to be completed with the encipheror
The application program of encryption, therefore, after another user is connected through other access devices with the present embodiment, by appropriate body
Divide after checking, you can the output mimeograph documents are opened with embedded application program, the different users that status is verified can be passed through by allowing
Need not install any program in computer can open printing archives.Because the archives of printing may be set to not editable lattice
Formula, the danger that can so avoid important information from being altered.
Understand that the present embodiment possesses following technical characteristic and reaches following technology effects based on preceding description：
1. providing the easy portable archives transmission medium with confidentiality, security, different user can be passed through and beats
India side formula, by customizing messages, column print is stored in the specific format, form is fixed the technique effect for reaching and avoiding altering.
2. the demand of paper is greatly decreased, puzzlement and the problem of existing paper information transmission are solved.
3. substantial amounts of information can be stored, whether general alert and resourceful file either needs the X-ray picture or disconnected of height parsing
Layer scanned picture, the technical characteristic carried using the present invention is fitted appropriate storage.
4. firmware stores the public and private key needed for encryption with storage area respectively, encryption efficiency is set more to be greatly reduced and crack
Risk.
5. difference, which can be opened, is stored in the storage element in the program of the output mimeograph documents, use by identity authentication is allowed
Person can directly open corresponding archives, reach the convenient technique effect used.
6. present invention can apply to the related important information with personal information, such as personal medical test report,
User can not only be provided to exempt to carry paper, the conveniences such as file can be inspected at any time, user can directly export any drawing and document
Case to the present apparatus preserves easy, and relevant information properly can be recorded and preserved, and authorization portions can will be obtained in hospital
Information digitalization, follows strictly the national and foreign standards of association area, and various inspections and the diagnostic result of patient can be showed completely,
Can reuse, it is quick and convenient, so as to reduce the inspection burden and Hospital operation cost of many patients, while it is dirty to reduce environment
Dye.
