In this step, it is necessary first to obtain the cleartext information of information to be transmitted before to information transfer, described to be transmitted Information can be obtained by user input or system directly gives;Described information to be transmitted can include:Word is believed Breath, pictorial information etc..
Described digital information is converted to least one set image code according to the first transformational rule by S102.
In this step, after getting the cleartext information of information to be transmitted, according to the first transformational rule by described digital information Be converted to least one set image code.Specifically, because cleartext information has the information of various codings it is possible to have Chinese, English, Other words, in order to various countries' word can be switched to unified coded format, prevent mess code, or identification less than feelings Condition, the unification of described cleartext information is converted to character code.
In the present embodiment, specifically described cleartext information is switched to base64 coding, base64 coding requirement is 38 Byte (3*8=24) is converted into the byte (4*6=24) of 46, mends two 0 afterwards before 6, forms 8 words The form of section.If remaining character, less than 3 bytes, is filled with 0, output character use '=', export after therefore encoding Text end it is possible that 1 or 2 '='.
So, cleartext information is converted to after character code, it will English alphabet occurs, numeral ,+,/,=these characters Mixed characters string encoding.
The unification of described cleartext information is converted to after character code, because being to need to be converted to character code in the present embodiment Color value carrys out blank map as therefore also needing in this step for character code to be converted to corresponding digital information, described numeral letter Breath refers to specific numerical value.
It is that the character string because of unicode coded format is by base64 coding is switched to unicode coding in the present invention One sets unified and unique binary coding, and therefore unicode coding is a piece of digital.
Here, because base64 coding is by English alphabet, numeral and+,/,=composition, therefore do not exist and be converted For exceeding the situation of computer binary system greatest measure 65535 after unicode, therefore, all codings switching to unicode are all Will be less than 65535.
Character code is converted to after digital information, each character code can correspond to set of number information, according to first Described digital information is converted to least one set image code by transformational rule.
Specifically, for one of which digital information, it is first determined the numerical value of described digital information;Determine each numeral Corresponding picture coding;Based on the numerical value of each digital corresponding picture coding described and every group digital information, by described every group Digital information is converted to corresponding picture coding;Corresponding picture coding is combined forming image code.
In the present embodiment, described image coding can include Morse coding, Morse coding be by point, draw, point and Pause between drawing, the short pause of each intercharacter (in point and draw between), between each word medium pause and sentence it Between long pause expressing series of characters.
When determining each digital corresponding picture coding, only need to determine that 0~9 corresponding Morse encodes, such as Shown in table 1:

From table 1 it follows that each numeral is made up of 5 Morse codings, waited using 3 between every group of numeral Representing interval, described waiting signal can be represented signal with ". ", thus all digital informations can be converted to mole This coded string, i.e. final image code.
Such as, two groups of digital number information are " 56 and 12 ", " 56 " can be converted to Morse according to above-mentioned logic Be encoded to " ... ..-.... ";" 12 " are converted to Morse and are encoded to " .----..--- ";So by " 56 and 12 " mole This coding is combined obtaining final Morse coded string, i.e. image code " ... ..-........----..--- ".
S103, generates image by described least one set image code.
In this step, after getting image code, whole image code only has ". " and two characters of "-", and this two characters Between time interval can be 10ms.
When image is generated by described least one set image code, travel through described image code first, obtain corresponding image Coding, corresponding picture coding refers to the corresponding picture coding of every group digital information, and described image coding includes the first figure As coding and the second picture coding;Here, described first image coding can be ". ", and the second picture coding can be "-".
Here, ". " representative is gone out, "-" represents bright;Therefore, it is possible to use completely black picture acute pyogenic infection of finger tip ". ", with white picture generation entirely Refer to "-", be thus completely black picture by described first image code conversion, described second picture coding is converted to white picture entirely ?;And completely black picture is 100ms with white picture transfer interval entirely.
Described first image coding is all converted to completely black picture, described second picture coding is all converted to entirely white After picture, described completely black picture and described entirely white picture can a picture queue, material is thus formed one with Morse coding On the basis of picture queue.
Then, DefaultMovieInfoProvider first image information pair is set up based on described picture queue As determining the frame number of broadcasting per second, and the frame number of broadcasting per second being arranged on described first image information by setFPS (100) In object.Here, the frame number of described broadcasting per second is to be determined by the length information of image code, and described image code refers to mole The frame number of broadcasting per second is therefore set to 10 frames by this coding.
After the frame number of broadcasting per second is set, determine described completely black picture and the totalframes of described entirely white picture, And totalframes is arranged in image object information;Here, described totalframes is the total bit determination according to image code, passes through setNumberOfFrames(jpgs.length);Totalframes is set.
Width and the height of image, described width, after totalframes sets up, are set in the first image object information Highly can be set according to different demands, in order to ensure terminal camera can accurately identify figure in the present embodiment Picture, width and height are set to 60*60 by acquiescence.
After above- mentioned information is set, based on the frame number of broadcasting per second, using image generation algorithm by described completely black figure The totalframes of piece and described entirely white picture generates image.
Specifically, it is possible to use the Jim2Mov method in java carrys out transition diagram picture, a newly-built first Jim2Mov file Folder, by the above-mentioned incoming described file of picture queue, then calls image generation algorithm saveMovie (MovieInfoProvider.TYPE_AVI_MJPEG);Start to read totalframes, generate image.

In this step, generate described image after, image is exported so that opposite equip. can by scan described image Lai Obtain described cleartext information.Described image can be single picture or video.
Opposite equip. only needs to be scanned this image by the terminal with client of the present invention can get in plain text letter Breath.Such as opposite equip. can be encrypted interaction in live video it is also possible to anywhere play, due to this image chi Very little smaller, therefore can choose a corner to play this image when playing other videos.
Embodiment two
The present embodiment provides a kind of method of parsing information, as shown in Fig. 2 methods described includes:
S201, receives and scanogram, obtains least one set image code.
In this step, because completely black picture and full the transfer interval between white picture be 100ms, therefore receiving terminal is in scanning figure During picture, extract a picture every 100ms in the stream of photographic head, after extraction finishes, you can obtain picture queue.
Due to being two kinds of pictures of black and white used in the present embodiment, and the aberration of two pictures is larger.And image In playing process, due to environment, temperature, display screen material etc. affects, and the color that photographic head obtains not is black and white purely Color, therefore when obtaining picture, also needs to determine the color of each picture in picture queue.
Specifically, it is determined that the color of each picture includes in picture queue:Obtain the color value of photo current;Determine completely black figure First Standard Colors value of piece, determines the second Standard Colors value of white picture entirely;Calculate described color value and the first Standard Colors The absolute value of the first difference of value, and the absolute value of the second difference of described color value and described second Standard Colors value;According to The absolute value of the absolute value of described first difference and described second difference determines the color of described photo current.
The absolute value of the absolute value according to described first difference and described second difference determines the color of described photo current, Including:When the absolute value of the first difference is less than the absolute value of the second difference, the color of photo current is defined as black;When When the absolute value of one difference is more than the absolute value of the second difference, the color of photo current is defined as white.
When obtaining the color value of photo current, it is possible to use bitmap.getPixel ();Method is obtaining.Here, because It is in Android device, described picture is typically made up of red (R), green (G), blue (B) three kinds of colors, and tri- kinds of colors of RGB are divided Do not show, therefore described in the present embodiment, the color value of picture refers to RGB color value, each color Shi You255Zhong stratum.
Here, the code reading the RGB color value of picture is as follows:
Int color=bitmap.getPixel (x, y);The colouring information of // acquisition current point
Int r=Color.red (color);// analyze the value of R in color
Int g=Color.green (color);// analyze the value of G in color
Int b=Color.blue (color);// analyze the value of B in color
The RGB color value of each picture can be obtained with above code.
In this manner it is possible to accurately determine the picture color in picture queue, obtain the picture team of black, white picture entirely Row.
Further, set up a character string queue, reuse the picture described in for searching loop in Android coding Queue, in traversal, when getting picture, judges that described picture is white or black, after determining that picture is white or black, Described completely black picture is converted to the first picture coding, described entirely white picture is converted to the second picture coding;In the present embodiment, Described first image coding and described second picture coding are Morse codings.Described Morse coding only has ". " and "-" two Character, will ". " represent goes out, "-" represent bright, therefore described first image coding can be ". ", the second picture coding can be "-".
After getting the first picture coding and the second picture coding, according to described first image coding and described second image Coding determines corresponding picture coding;Described image coding is combined obtaining described least one set image code.
Described least one set image code is converted to cleartext information according to the second transformational rule by S202.
In this step, after getting the corresponding image code of all pictures, first according to the second transformational rule by described extremely Few one group of image code is converted to digital information, including:
According to default extracting rule, described image code is split as least one set picture coding, determines that each numeral is right The picture coding answered.In the present embodiment, described image coding can include Morse coding, Morse coding be by point, draw, Medium pause and sentence between the short pause of pause between putting and drawing, each intercharacter (between putting and drawing), each word Between son, long pause is expressing series of characters.

The absolute value of the absolute value according to described first difference and described second difference determines the color of described photo current, Including:When the absolute value of the first difference is less than the absolute value of the second difference, the color of photo current is defined as black;When When the absolute value of one difference is more than the absolute value of the second difference, the color of photo current is defined as white.
When obtaining the color value of photo current, it is possible to use bitmap.getPixel ();Method is obtaining.Here, because It is in Android device, described picture is typically made up of red (R), green (G), blue (B) three kinds of colors, and tri- kinds of colors of RGB are divided Do not show, therefore described in the present embodiment, the color value of picture refers to RGB color value, each color Shi You255Zhong stratum.
Here, the code reading the RGB color value of picture is as follows:
Int color=bitmap.getPixel (x, y);The colouring information of // acquisition current point
Int r=Color.red (color);// analyze the value of R in color
Int g=Color.green (color);// analyze the value of G in color
Int b=Color.blue (color);// analyze the value of B in color
The RGB color value of each picture can be obtained with above code.

According to default extracting rule, described image code is split as least one set picture coding, determines that each numeral is right The picture coding answered.In the present embodiment, described image coding can include Morse coding, Morse coding be by point, draw, Medium pause and sentence between the short pause of pause between putting and drawing, each intercharacter (between putting and drawing), each word Between son, long pause is expressing series of characters.
When determining each digital corresponding picture coding, only need to determine that 0~9 corresponding Morse encodes, such as Shown in table 1:
Table 1
From table 1 it follows that each numeral is made up of 5 Morse codings, and using 3 etc. between every group of numeral Treat signal to represent interval, described waiting signal can be represented with ". ".So extract rule can be:In every group of image code Extract once at interval of 5 characters, to obtain least one set picture coding.
So, extract once at interval of 5 characters in every group of picture coding, the corresponding number of this character is inquired about according to table 1 Word, will obtain the character string being made up of numeral and waiting signal ". " after inquiry finishes.After obtaining this character string, will be to wait Signal ". " to cut character string for boundary line, just obtains data that one group of group is made up of numeral, so can be based on described every number The corresponding picture coding of word and every group of picture coding, picture coding is converted to digital information.
Such as image code is " ... ..-........----..--- ", and described image code is split as picture coding respectively For:“.....-....”…“.----..---”;According to table 1, the corresponding numeral of picture coding is respectively 56, three waits Signal " ... " and 12;Finally understand, digital information is 56 and 12.
In the present embodiment, set unified and unique binary system because the character string of unicode coded format is one Coding, therefore unicode coding is a piece of digital.So the present embodiment is that image code is converted to unicode coding realization figure Conversion as code to digital information.
After getting digital information, the second converting unit 43 is additionally operable to for described digital information to be converted to character code.
Specifically, in the present embodiment, the 4th converting unit 43 is the coding by unicode code conversion for base64:
Transcode is as follows:
4th converting unit 43 uses above-mentioned code, and the data of return is exactly the character-coded data of Base64.
After getting character code, described 4th converting unit 43 is additionally operable to be converted to described character code to be stated clearly Civilian information.
After getting character code, described 4th converting unit 43 utilizes code:
Base64.encodeToString(str.getBytes(),Base64.DEFAULT);
Just the character code of Base64 can be converted to cleartext information.
So, just complete the process of parsing information.
