Specific embodiment
Hereinafter, certain exemplary embodiments are simply just described.As one skilled in the art will recognize that
Like that, without departing from the spirit or scope of the present invention, described embodiment can be modified by various different modes.
Therefore, attached drawing and description are considered essentially illustrative rather than restrictive.
Fig. 1 shows the flow chart of watermark information wiring method according to an embodiment of the present invention.As shown in Figure 1, this method packet
It includes:
S11, according to scheduled Selection Strategy, at least two fields are chosen from initial data;
S12, determination is corresponding with watermark information puts in order;
S13, according to putting in order, at least two fields of selection are ranked up.
It should be noted that in step S13 according to the sorting operation that puts in order only for the word chosen in initial data
Section, other unselected fields are remained unchanged according to default sequence in initial data.It is available to include according to step S13
The data of watermark information.Data comprising watermark information include according to the field of the selection for the sequence that puts in order, and according to silent
Recognize other fields that sequence remains unchanged.Example, initial data are { A W B X C Y D Z }, and each letter indicates a field,
The field chosen from initial data is [A B C D], the field of selection according to being [D C B A] after the sequence that puts in order, because
It is { D W C X B Y A Z } that this, which obtains the data comprising watermark information,.
In one embodiment, the sequence of at least two fields of selection does not influence the content of initial data.
Be utilized some data type (such as structural data of plain text) be to the sequence of field itself not
It is required that characteristic, i.e. the sequence of field do not influence the expression of data content itself.Watermark information is encoded using order of the field, both
The readability of data is not influenced, and will not increase any extra field newly, so that the user of data perceives less than watermark.
In one embodiment, at least two fields of selection are the leaf node data in same node, to avoid
Influence to the content expression of data, leaf node are the node of not child node.In addition, usually being needed when selecting node
Consider the abundant degree of the field of the node, usually chooses most 20 feature fields of at least six.
For example, the kind number of the mode that puts in order of 21 fields is if the preset quantity chosen is 21 fields
2 64 powers are had exceeded, that is, the type for choosing the watermark information that 21 fields can map has exceeded 2 64 powers.Cause
This, is generally up to about and chooses 20 fields.
In one embodiment, at least two fields chosen in step S11 include plain text structural data or two
System structural data.I.e., it is only necessary to meet selection the corresponding data type of field be plain text structural data or two into
Structural data processed.Initial data can be plain text structural data or binary structured data, alternatively, original number
Partial data in is plain text structural data or binary structured data.
A kind of example, plain text structural data can be JSON (JavaScript Object Notation) data.
Binary structured data can be MsgPack (MessagePack) data or BSON (Binary Serialized
Document Format) data.
It should be explained that:
JSON is a kind of data interchange format of lightweight.Based on the ECMAScript (js that European Computer association formulates
Specification) a subset, data are stored and indicated using the text formatting for being totally independent of programming language.
MessagePack is one based on the efficient object serialization class libraries of binary system, be can be used for across speech communication.
MessagePack data similar to JSON data, can between multilingual perhaps switching fabric object;But more than JSON data
It is quickly also lighter and handier.
BSON is a kind of computer data exchange format, is mainly used as MongoDB database (based on distributed document
The database of storage) in data storage and network transmission format.BSON is a kind of binary representation, can be used to indicate letter
It is each in single data structure, Associate array (being known as " object " or " document " in MongoDB database) and MongoDB database
Kind data type.For the name of BSON because of JSON, meaning is Binary JSON (binary system JSON).
In one embodiment, scheduled Selection Strategy may include three kinds in step S11:
The first, chooses the field of whole child nodes of destined node.The word of whole child nodes suitable for destined node
The few scene of section sum.
Alternatively, second, choose the field of the preset quantity of the lexcographical order of destined node.Whole suitable for destined node
The very more scene of the field sum of child node.
Wherein, in mathematics, lexcographical order (also referred to as vocabulary sequence, lexicographic order, lexicographic order or lexicographic order) can be with
Refer to the method that word arranges in alphabetical order.
Alternatively, the third, chooses at least two specified fields of default list.The field chosen by presetting list,
Compared to aforementioned two ways, the field that the method is chosen does not have rule that can follow, and the field of selection and other fields can be mixed
Confuse, increases the difficulty that the field of selection is cracked.
In general, structural data can be distributed with tree structure, forming one by a limited node of n (n > 0) has level
The set of relationship.Child node where field selected by above-mentioned three kinds of modes is subordinated to same node.Because if the field chosen
Different nodes are subordinated to, then the node of field institute subordinate is also converted after converting the sequence of field, influence to count
According to correct reading.For example, using personage as node, son A1 is associated under father A by data by taking the family tree of human society as an example
With daughter A2, son B1 and daughter B2 is associated under father B, if exchanging the sequence or subordinate father A of son A1 and daughter A2,
The accuracy of family tree is had no effect on, if exchanging the sequence of son A1 and son B1, the father of subordinate changes at this time, affects
The accuracy of family tree.
In one embodiment, in step S12, one kind, which puts in order, uniquely corresponds to a kind of watermark information, is convenient for basis
This, which puts in order, can determine that corresponding watermark information.Preferably, putting in order with watermark information is one-to-one relationship.It puts in order
It is prestored with the corresponding relationship of watermark information, the corresponding relationship that step S12 is prestored according to this, determination is corresponding with watermark information
It puts in order;Or, the corresponding relationship is stored after step S12 has determined put in order corresponding with watermark information.

5.[a,d,b,c]
6.[a,d,c,b]
7.[b,a,c,d]
8.[b,a,d,c]
9.[b,c,a,d]
10.[b,c,d,a]
11.[b,d,a,c]
12.[b,d,c,a]
13.[c,a,b,d]
14.[c,a,d,b]
15.[c,b,a,d]
16.[c,b,d,a]
17.[c,d,a,b]
18.[c,d,b,a]
19.[d,a,b,c]
20.[d,a,c,b]
21.[d,b,a,c]
22.[d,b,c,a]
23.[d,c,a,b]
24.[d,c,b,a]
For the field { a, b, c, d } of selection, if the ID of some user is 11, then it is suitable according to the corresponding arrangement of the ID
Sequence, it is available { b, d, a, c } after foregoing fields rearrangement.
