Description
Technical field
The invention belongs to mobile application management domains, and in particular to a kind of dark watermark display methods in mobile terminal.
Background technique
Quick with intelligent machine is popularized, and mobile office tends to normality, how to prevent business data from leaking in mobile terminal urgent
In the eyebrows and eyelashes.By adding watermark on application interface and document, have become the universal way of protection data.
Existing mobile terminal watermark function is watermark content to be directly displayed on mobile phone application interface, and there are two ask for this
Topic:
1, watermark content is too obvious, interferes user's normal reading, and user experience is bad；
2, watermark content directly displays out, is easy to be forged by criminal, brings hidden danger to enterprise.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention proposes a kind of dark watermark display methods in mobile terminal, solves existing water
The problem of print technology makes watermark content excessively obvious, easily interference user's normal reading, influences user experience, while can also solve
Certainly existing watermark content is easy the problem of being forged by criminal, bringing hidden danger to enterprise.
The present invention to achieve the above object, is implemented with the following technical solutions:
A kind of dark watermark display methods in mobile terminal, comprising the following steps:
Step 1: after watermark content code conversion, being placed in matrix；
Step 2: matrix is generated on application interface.
Further, as optimal technical scheme, the detailed process of the step 1 are as follows:
Step 1-1: by the corresponding watermark information sequence A=of watermark content { a1, a2, a3 ... an }, data are generated after coding
It flows B={ b1, b2, b3 ..., bn }；
Step 1-2: according to organization regulation M, data stream B is placed in matrix E.
Further, as optimal technical scheme, in the step 1-1, the data stream B is watermark information sequence A's
Digitized representations.
Further, as optimal technical scheme, it is described n times mapping processing first is carried out to data stream B after, obtain data flow
Cn, then data flow Cn is placed in matrix E, wherein n is positive integer.
Further, as optimal technical scheme, in step 1-2, by organization regulation M by data stream B with binary system or
The ternary mode of person stores in matrix E.
Further, as optimal technical scheme, in step 1-2, matrix E is the matrix of M*N, wherein M and N are
In or greater than 3 positive integer.
Further, as optimal technical scheme, in step 1-2, in the matrix E, by the color and size of point come
Indicate different data.
Further, as optimal technical scheme, in step 1-2, traffic flow information, verification letter are included in the matrix E
Breath and delimiter information.
Compared with prior art, the present invention have the following advantages that and the utility model has the advantages that
(1) watermark content of the invention is only shown on application interface in a manner of dot matrix, compared to traditional display text
Watermark, the present invention is shown on view will not be excessively obvious, is not easy to cause user's note that so as to avoid interference user
It reads, the more comfortable reading experience of user is provided.
(2) present invention uses code conversion mode to show watermark information on application interface in a manner of dot matrix, other
People in the case where not knowing coding and conversion regime, can not counterfeit watermarking content, to provide the user with safe experience.
Detailed description of the invention
Fig. 1 is flow chart of the method for the present invention.
Specific embodiment
The present invention is described in further detail below with reference to embodiment, embodiments of the present invention are not limited thereto.
Embodiment 1:
As shown in Figure 1, a kind of dark watermark display methods in mobile terminal described in the present embodiment, comprising the following steps:
Step 1: after watermark content code conversion, being placed in matrix；
Step 2: matrix is generated on application interface.
Specifically, the detailed process of the step 1 of the present embodiment are as follows:
Step 1-1: by the corresponding watermark information sequence A=of watermark content { a1, a2, a3 ... an }, data are generated after coding
It flows B={ b1, b2, b3 ..., bn }；
Step 1-2: according to organization regulation M, data stream B is placed in matrix E.
In step 1-1, watermark information sequence A corresponding is watermark content, belongs to content of text, by watermark information sequence
A is converted into data stream B, is that content of text is converted into digital information in fact, and watermark information sequence A to data stream B is digitlization
Process, data stream B are the digitized representations of watermark information sequence A, for example unicode coding can be used to complete watermark information sequence
Arrange the conversion of A to data stream B.
In the present embodiment, after first can carrying out n times mapping processing to data stream B, data flow Cn is obtained, then by data flow Cn
It is placed in matrix E, wherein n is positive integer.For example primary mapping obtains data flow C1 after data stream B carries out 1 mapping processing,
Data flow C1 is placed in matrix E again, there are a functional relation, C=f (B), this function f with data stream B by data flow C1
() is equivalent to and encrypts to data stream B, carries out after repeatedly mapping, is repeatedly encrypted relative to data stream B, even if he
People gets dot matrix form, it is also desirable to while organization regulation M is obtained, data flow Cn counter could be released, is then knowing function f
Data stream B can be just obtained in the case where (), it is clear that complexity among these as one can imagine, to substantially increase decoding difficulty,
Provide safety.
In the present embodiment, data stream B can be stored in a manner of any system according to setting by organization regulation M
Into matrix E, it is preferred to use binary system or ternary mode store in matrix E.Matrix E is the matrix of M*N, and M and N are equal
For the positive integer equal to or more than 3, M and N can be the same or different, in simple terms, if matrix E is dot matrix 3*3, number
It is stored in dot matrix 3*3 in a binary fashion according to stream B；If matrix E is dot matrix 5*7, data stream B stores arrive in a binary fashion
In dot matrix 5*7.In matrix E, a point can indicate different data with different colors, different sizes, in matrix E
It further include check information and delimiter information etc., the information of carrying can oneself definition in addition to carrying traffic flow information.
The above is only presently preferred embodiments of the present invention, not does limitation in any form to the present invention, it is all according to
According to technical spirit any simple modification to the above embodiments of the invention, equivalent variations, protection of the invention is each fallen within
Within the scope of.
