Description

INFORMATION CODING METHOD, SYSTEM AND COMPUTER-READABLE MEDIUM

BACKGROUND

[0001] Semantic data refers to data that can be interpreted meaningfully by a machine without human intervention. A semantic data model is typically a software engineering model based on relationships between stored symbols, or objects, and the real world. Data is organized based on binary models of objects, usually in groups of three parts: two objects and a relationship between the two objects. For example, a data organization that represents a cup sitting on a table might look like "cup table." The objects, i.e., cup and table, are interpreted with regards to their relationship, i.e., sitting on. The data is organized linearly, and the position of the objects reveals to software that the cup is sitting on the table and not the other way around. Accordingly, semantic data systems are designed to represent the real world as accurately as possible within the data set, and objects in the data set are organized linearly and hierarchically to give meanings to what they represent.

[0002] In a cloud-computing environment, data used for management, control, communication and other applications may be sent along with general messages that are transmitted over the network. Such data is typically short, and is discretely affixed to or embedded in the carrying message.

SUMMARY

[0003] In at least one embodiment, a method includes pretreating a textual message that includes a plurality of semantic sentences used for generating a sequence of binary bits, with each bit of the sequence of binary bits corresponding to a respective one of the semantic sentences, determining that the textual message is suitable to carry a code of a plurality of bits therein, and embedding the code in a subset of the plurality of semantic sentences in response to the determining.

In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features will become apparent by reference to the drawings and the following detailed description.

DETAILED DESCRIPTION

[0011] In the following detailed description, reference is made to the accompanying drawings, which form a part of the description. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. Furthermore, unless otherwise noted, the description of each successive drawing may reference features from one or more of the previous drawings to provide clearer context and a more substantive explanation of the current example embodiment. Still, the example embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the figures, may be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein. [0012] Described herein are systems, apparatuses, computer program products, methods, and techniques related to embedding a code into a textual message based on semantic data reasoning. Some example implementations described herein include pre-treating the textual message by segmenting the textual message into a plurality of individual semantic sentences and determining whether the textual message is suitable to carry the data. When it is determined that the textual message is suitable to carry the code, a subset of the plurality of semantic sentences is selected and the semantic sentences of the selected subset are tagged. A first knowledge base containing private information is utilized in the selection and tagging of semantic sentences. The code is embedded in the textual message, thus encoding the textual message, through the selection and tagging of select semantic sentences of the textual message. The encoded textual message is transmitted to a receiving party which can decode the encoded textual message to obtain the code using the first knowledge base or a second knowledge base that is a duplicate of the first knowledge base.

OVERVIEW

[0013] Typically, the content of a message implies or reflects certain private information about the author of the message. For example, a teacher can generally determine whether a student has mastered a given subject from the student's answers to questions of a test. In other words, the answers provided by the student reflect a level of knowledge of the student with respect to the subject being tested. As another example, when a user logs into a system, the user may be asked to answer a short question such that a correct answer to the short question implies the authenticity or identity of the user. Of course, such scenarios are not intended to be limiting in any manner. Instead, it is to be understood that information implied in a given message can be reasoned, or deduced, from each of one or more semantic sentences of the given message.

[0014] Assuming a result of deducing a conclusion from a semantic sentence can be treated as a Boolean value, a deduced conclusion consistent with the truth behind the semantic sentence can be represented by a bit value of 1 and a deduced conclusion inconsistent with the truth behind the semantic sentence can be represented by a bit value of 0. Thus, a message containing multiple semantic sentences can be seen and treated as a string of bits of 0 and 1 when each of the semantic sentences of the message is deduced to a conclusion that is either consistent or inconsistent with the truth. For instance, as an illustration using public knowledge, a message M containing the following three sentences can be expressed mathematically as M =

{0, 1, 0}: "There are more days in February than in March. There are fifty states in the United States of America. The weather is generally colder in summer than in winter." This is because the deduced conclusion of the first sentence, si, is inconsistent with the truth, the deduced conclusion of the second sentence, s2, is consistent with the truth, and the deduced conclusion of the third sentence, s3, is inconsistent with the truth.

[0015] A knowledge base that contains privileged information, such as private information about an author of a message, for example, may be used to determine whether a deduced conclusion is consistent with the truth behind a respective semantic sentence. Accordingly, when a message has a multiple number of semantic sentences in a sufficiently large number as explained below, a given code of one or more bytes can be embedded, or carried, in a select number of semantic sentences of the message, in which the selected semantic sentences are selected in a sequence such that the bit value of the deduced conclusion of each selected semantic sentence represents a corresponding bit of the one or more bytes of the embedded code. The selected semantic sentences are tagged, or otherwise marked or highlighted, to identify them as the selected ones of the plurality of semantic sentences of the message that carry the code. The encoded message can be transmitted to a receiving party that has access to a knowledge base having the same privileged information, and the receiving party can recover the code by using the knowledge base.

[0016] Fig. 1 shows an example scheme 100 of information coding based on semantic data reasoning, arranged in accordance with at least some embodiments described herein.

[0017] According to scheme 100, on a sending side, a message may be a textual message containing one or more semantic sentences and encoded to carry a code as an encoded message, using a first knowledge base, and transmitted to a receiving side. On the receiving side, a second knowledge base may be used to decode the encoded message to obtain the original message. Mathematically, the message can be denoted as M, the first knowledge base can be denoted as K, the code can be denoted as I, and the encoded message can be denoted as M'. M

= {si, s₂, Si, ...}, and s, is an arbitrary semantic sentence among the one or more semantic sentences of M. K is used in the deducing process and the deduced conclusion of s, may be consistent or inconsistent with the truth behind the respective semantic sentence, corresponding to Boolean value 1 and 0, respectively. I can be expressed as a sequence of binary bits such as I = bib₂...bi, where b, is the i^th bit of I. For instance, a code I = 1101 can be embedded in the encoded message M' = {0, 1, 0, 1, 1, 0, 1, 0, 0, 1} when the Boolean values of the deduced conclusions of sentences s₄ through s₇ reflect those of the four bits of code I. [0018] Further, the privileged information stored in the first knowledge base and the privileged information stored in second knowledge base may be identical. In at least some embodiments, the first knowledge base and the second knowledge base are the same knowledge base accessible by both a sending party and a receiving party. In at least some other embodiments, the second knowledge base is a duplicate copy of the first knowledge base. For example, the first knowledge base and the second knowledge base may be separate knowledge bases that are synchronized periodically so that the privileged information stored in the first knowledge base and the privileged information stored in the second knowledge base are identical. In the description herein, the mathematical symbol K is used to represent either the first knowledge base or the second knowledge base.

[0019] Example scheme 100 may include one or more operations, actions, or functions as illustrated by one or more blocks 104, 106, 108, 110, and/or 112, with references to one or more of a message 102, a code 114, a knowledge base 116, and/or a knowledge base 118. Although scheme 100 is illustrated as discrete blocks, various blocks may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation. Processing may begin at block 104.

[0020] Block 104 (Pretreatment) may include pretreating message 102, or M, by preparing message 102 for determination of whether message 102 is suitable to carry code 114 and for subsequent encoding of message 102 to carry code 114 therein if it is determined that message 102 is suitable to carry code 104. For example, a processor or a computing device on the sending side (e.g., operated by a sending party) may pretreat M by segmenting M into a multiple number of individual semantic sentences, s_h s₂, ... s, .... In succession, the processor may deduce a respective conclusion from each semantic sentence and compare the conclusion to the privileged information in /( to result in a binary bit in sequence R, namely R = r₁r₂...r„ for which r, is a bit corresponding to a result of comparison of the deduced conclusion and the privileged information in K with respect to semantic sentence s,. The value of r, is 1 if the result of comparison is consistent, and 0 if inconsistent.

[0021] By way of example, suppose a receiving party, e.g., Jack, has one daughter whose name is Agnes. Then, if M includes a sentence s, that states "Jack has a daughter whose name is Jessica", then the result of a comparison of the deduced conclusion (i.e., the name of Jack's daughter is Jessica) and the privilege information in K (i.e., the name of Jack's daughter is Agnes) has a value of 0 since the deduced conclusion is inconsistent with the privileged information in K. This process can be formalized by using Description Logics, which is the logical foundation of semantic data, namely:

K = { Jack 0 = 1 hasDaughter, hasDaughter(Jack, Agnes)} s,:= hasDaughter(Jack, Jessica)

On the sending side, /C U {s, } =-L .

[0022] Thus, s, as deduced is inconsistent, and is depicted as r, 0 or r, = 0. Processing may proceed from block 104 to decision block 106.

[0023] Decision block 106 (Message Suitable for Coding?) may include determining whether message 102 is suitable to carry code 114, as not all messages may be able to carry code 114 under scheme 100. If message 102 is determined to be suitable to carry code 114, processing under scheme 100 may proceed to block 108; otherwise, processing may end. Under scheme 100, two factors may be considered in determining whether message 102 is suitable to carry code 114, namely: length and semantic richness of message 102. For example, the processor may determine message 102 to be too short if message 102 does not have enough semantic sentences therein to represent the number of bits in code 114. On the other hand, the processor may determine that message 102 has a sufficiently large number of semantic sentences when the number of the semantic sentences in message 102 is greater than the number of bits in code 114. Moreover, if message 102 does not have sufficient semantic richness to support coding or embedding code 114 into message 102, the processor may determine that message 102 is not suitable to carry code 114 even if message 102 is long enough with a large number of semantic sentences.

[0024] In determining whether the length of message 102 is sufficient, example mathematical operations that can be performed are as follows:

1) Sum up the number of semantic sentences in M, denoted as n, for which n = | | .

2) Calculate the number of bits in /, denoted as m, for which m is equal to 4 times the number of characters in /, including space and other invisible symbols.

3) If the relationship between m and n is satisfied with equation (1) below, then the length of message 102 is determined to be sufficiently long: n≥C_r - m + c (1)

Here, C_r is the reduction ratio of compression algorithm which may be adopted in information transition. If no compression algorithm is used, then C_r = 1. c is a redundancy number.

[0025] The determination of whether the semantic richness of message 102 is sufficient is a rough estimation. Even if the length of message 102 is long enough, low semantic richness can lead to failure in encoding message 102 with code 114. For example, when M has R = 0101111, / = 1000 cannot be coded into M even though the length of M is longer than /. An example pseudo code that tests the semantic richness of M for / is as follows:

Input: Rtemp, R, I, n, m, n≥ m

Output: num, the semantic richness

Start:

Let R_temp = r_!r₂...r_mi i = 1, num = 0

lf( < n)

{

i + +;

Rtemp left shift one bit and then append r_m+l to R_temp;

lf(match(/?_temp, )) num + +;

Output num,;

}

End.

[0026] The function "match(s£/7/7g_!, string2)" is defined to determine how many times string2 matches stringl. Any one of numerous class match algorithms can be used to design this function, such as brute-force (BF), Knuth-Morris-Pratt (KMP), Boyers-Moore (BM) and so on. Once num≥ 1, / can be coded into M. When a gap of semantic richness between M and / is not large (e.g., not exceeding 5% of the number of bits in /), some tautology may be used to compensate the gap, for instance, by adding one or more accessorial sentences into message 102. For example, semantic data sentence such as "1 = 1", which would result in a deduced conclusion of "true" with a Boolean value of 1, or a repetition of one of the sentences of M having a Boolean value of 1 for the deduced conclusion may be used complementarily when there lacks a suitable semantic sentence. If it is determined that message 102 is not suitable to carry code 114, then processing under scheme 100 may end as message 102 cannot be utilized to carry code 114. Processing may return to block 104 for a new message if and when the new message is available as a candidate message to carry code 114.

[0027] Block 108 (Encode the Message) may include tagging or otherwise marking message 102 to embed code 114 in message 102. For example, the processor may select some of the semantic sentences of message 102 such that the respective binary bit of comparison result of each of the selected semantic sentences represents a corresponding bit of code 114. In at least some embodiments, each of the selected semantic sentences may be appended with a prefix or a suffix to tag the selected semantic sentences. This way, as a decoding process on the receiving side is to be performed on just those semantic sentences in encoded message /7' that are tagged or otherwise marked, considerable time can be saved. An example of tagging a selected semantic sentence is as follows:

Original sentence: Jack has a daughter whose name is Jessica.

Tagged sentence: HJack has a daughter whose name is Jessica.

[0028] Here, "S3" is a label used for tagging to indicate the immediately following sentence is a selected semantic sentence. Processing may proceed from block 108 to block 110.

[0029] Block 110 (Transmit Encoded Message) may include transmitting encoded message M', which carries / therein, from the sending party to the receiving party. For example, the processor on the sending side may cause the encoded message M' to be transmitted to the receiving side (e.g., a computing device operated by a receiving party) via any suitable means, e.g., over a wired medium, wireless medium or a combination thereof. As the encoding of message M to embed code / therein may be performed on the semantic level, no additional channel coding is necessary. Processing may proceed from block 110 to block 112.

[0030] Block 112 (Decode the Encoded Message) may include decoding M' by segmenting M' into a multiple number of individual semantic sentences. To recover the code /, a processor or a computing device on the receiving side (e.g., operated by the receiving party) may deduce a conclusion from each of those semantic sentences that are tagged, and compare the deduced conclusion to the privileged information in second knowledge base 118 with respect to the respective semantic sentence.

EXAMPLE APPLICATIONS

[0031] There are numerous applications in which scheme 100 can be implemented, including but not limited to, for example, data classification, primary rate interface (PRI) management and authentication. As an example of data classification applications, a message may be classified into, for example, 16 classes denoted by binary bits 0000 through 1111. The classes may be used to identify the type of content of the message. For example, class 1 (e.g., 0001 in binary) may be sports, class 2 (e.g., 0010 in binary) may be politics, class 3 (e.g., 0011 in binary) may be history, class 4 (e.g., 0100 in binary) may be economics, and so on. Accordingly, four semantic sentences may be selected from M to represent the corresponding four bits, with the corresponding bit r, of each of the four selected semantic sentences representing the respective bit of the 4-bit classification. As an illustrative example, M is assumed to be classified as a message of class 8, which is denoted as 1000 in binary, and the four selected semantic sentences are s₂, s₃, s₅ and s₁₂. A comparison of the deduced conclusion of each of s₂, s₃, s₅ and s₁₂ with K yields a consistent result for s₂ (i.e., r = 1), an inconsistent result for s₃ (i.e., r₂ = 0), an inconsistent result for s_s (i.e., r₃ = 0), and an inconsistent result for s₁₂ (i.e., r₄ = 0). Thus, the four semantic sentences s₂, s₃, s₅ and s₁₂ are selected to carry /, in this case classification of M, which is 1000. A special tag is appended as prefix to each of semantic sentences s₂, s₃, s₅ and s₁₅, and the encoded message M' is transmitted to a receiving party. The receiving party of M' compares the deduced conclusion of those semantic sentences that are tagged, namely s₂, s₃, s₅ and s₁₂, with Kto obtain the code /, which is 1000, indicating content of M is classified as class 8.

[0032] As an example of PRI management applications, a message is assigned one of eight PRI levels that are respectively denoted by binary bits 0000 through 0011. Four semantic sentences are selected from M to represent corresponding bits of the PRI level of M. The encoded message, M', is transmitted over a network and each node in the path decodes M' to determine the PRI level of M to process M according to the corresponding PRI procedure.

[0033] As an example of authentication applications, the term "king" is the authenticated term and is divided into four characters, namely "k", "\" , "n" and "g". The corresponding ASIIC code in binary bits are 01101011, 01101001, 01101110 and 01100111, respectively, for a total of thirty-two bits. Accordingly, thirty-two sentences are selected from M to represent the ASIIC binary bits of the authenticated term. On the receiving side, a received message passes the authentication when the message includes semantic sentences that yield comparison results r₁r₂...r₃₂ that are identical to the ASIIC code of "king" in binary bits.

EXAMPLE PROCESSES

[0034] Fig. 2 shows a processing flow 200 for information coding based on semantic data reasoning, arranged in accordance with at least some embodiments described herein.

[0035] Example processing flow 200 includes one or more operations, actions, or functions as illustrated by one or more of blocks 202, 204 and 206. Although illustrated as discrete blocks, various blocks may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation. Further, processing flow 200 may be implemented by software, hardware, or a combination of software and hardware in any type of computing device, such as example computing device 500 to be described below. For illustrative purposes, the operations described below are performed by a processor of a computing device. Processing may begin at block 202.

[0036] Block 202 (Pretreat A Textual Message) may include pretreating a textual message that includes a multiple number of semantic sentences used for generating a sequence of binary bits, with each bit of the sequence of binary bits corresponding to a respective one of the semantic sentences. For example, a processor or a computing device on the sending side (e.g., operated by a sending party) may pretreat message 102 in two stages. First, message 102 may be segmented into a multiple number of semantic sentences as M = {s^ s₂, ... s,j. Then, the multiple semantic sentences may be analyzed to generate the sequence of binary bits. In at least some embodiments, in analyzing the multiple semantic sentences, the processor may generate a binary 0 when a concept conveyed by a respective one of the semantic sentences is false based on information in a knowledge base, such as knowledge base 116. Conversely, the processor may generate a binary 1 when the concept conveyed by the respective one of the semantic sentences is true based on the information in the knowledge base. In at least some embodiments, the information in the knowledge base is privileged information such as private information that is known to a sending party and a receiving party but not to others. Processing flow 200 may proceed from block 202 to block 204.

[0037] Block 204 (Message Suitable for Coding?) may include determining whether the textual message is suitable to carry a code of a multiple number of bits therein. If message 102 is determined to be suitable to carry code 114, then processing flow 200 may proceed to block 206; otherwise, processing flow 200 may end. For example, the processor may determine that message 102 is suitable to carry code 114, which has a multiple number of bits, when a length of message 102 is suitable to carry code 114 and semantic richness of message 102 is sufficient to carry code 114. In at least some embodiments, the processor may determine that the length of message 102 is suitable to carry code 114 based on a number of factors. Such factors may include, for example: (1) a quantity of the multiple number of semantic sentences in message 102, (2) a quantity of the multiple number of bits in code 114, and (3) that a sum of a redundancy number and a product of the quantity of the multiple number of semantic sentences in message 102 and a reduction ratio of compression algorithm is less than the quantity of the multiple number of bits in code 114. In at least some embodiments, in determining that the semantic richness of message 102 is sufficient to carry code 114, the processor may compare code 114 to the sequence of binary bits and determine that the multiple number of bits of code 114 can be represented by a corresponding number of binary bits of the sequence of binary bits. Processing flow 200 may proceed from block 204 to block 206.

[0038] Block 206 (Embed the Code in the Textual Message) may include embedding the code in a subset of the multiple semantic sentences in response to determining that the textual message is suitable to carry the code. For example, in embedding code 114 in a subset of the semantic sentences of message 102, the processor may select the subset of the multiple number of semantic sentences to carry code 114 in message 102 such that a pattern of the binary bits corresponding to the subset of the multiple number of semantic sentences match a pattern of the multiple number of bits of code 114. Further, the processor may tag the subset of the multiple semantic sentences such that the binary bit corresponding to a respective one of the tagged semantic sentences indicates a respective one of the bits of code 114. In at least some embodiments, the processor may tag the tagged semantic sentences by prefixing each of the tagged semantic sentences with a label. In at least some other embodiments, the processor may tag the tagged semantic sentences by suffixing each of the tagged semantic sentences with a label. In still some other embodiments, the processor may tag the tagged semantic sentences by highlighting the tagged semantic sentences in a way that is recognizable by the receiving party.

[0039] In at least some embodiments, processing flow 200 may further include transmitting the textual message with the code embedded therein. For example, after encoding message 102 with code 114, the processor may transmit, or cause the associated computing device to transmit, the encoded message to the receiving party.

[0040] Fig. 3 shows a processing flow 300 for information coding based on semantic data reasoning, arranged in accordance with at least some embodiments described herein.

[0041] Example processing flow 300 includes one or more operations, actions, or functions as illustrated by one or more of blocks 302, 304, 306 and 308. Although illustrated as discrete blocks, various blocks may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation. Further, processing flow 300 may be implemented by software, hardware, or a combination of software and hardware in any type of computing device, such as example computing device 300 to be described below. For illustrative purpose, the operations described below are performed by a processor of a computing device. Processing may begin at block 302.

[0042] Block 302 (Segment A Textual Message) may include segmenting a textual message into a multiple number of semantic sentences. For example, a processor or computing device may segment message 102 into a multiple number of semantic sentences as M = {s^ s₂, ... s,j. Processing flow 300 may proceed from block 302 to block 304.

[0043] Block 304 (Analyze Semantic Sentences of the Textual Messages) may include analyzing the multiple semantic sentences to generate a sequence of binary bits, with each bit of the sequence of binary bits corresponding to a respective one of the semantic sentences. In at least some embodiments, in analyzing the multiple semantic sentences of message 102, the processor may generate a binary 0 when a concept conveyed by a respective one of the semantic sentences is false based on information in a knowledge base, such as knowledge base 116. Conversely, when a concept conveyed by the respective one of the semantic sentences is true based on information in the knowledge base, the processor may generate a binary 1. In at least some embodiments, the information in the knowledge base may be privileged information such as private information that is known to a sending party and a receiving party but not to others. Processing flow 300 may proceed from block 304 to block 306.

[0044] Block 306 (Message Suitable for Coding?) may include determining whether the textual message is suitable to carry a code of a multiple number of bits therein. If the textual message is determined to be suitable to carry the code, then processing flow 300 may proceed to block 308; otherwise, processing flow 300 may end. For example, the processor may determine that message 102 is suitable to carry code 114 therein when the processor determines that a length of message 102 is suitable to carry code 114 and that semantic richness of message 102 is sufficient to carry code 114. In at least some embodiments, the processor may determine that the length of message 102 is suitable to carry code 114 based on a number of factors. Such factors may include, for example: (1) a quantity of the multiple number of semantic sentences in message 102, (2) a quantity of the multiple number of bits in code 114, and (3) that a sum of a redundancy number and a product of the quantity of the multiple number of semantic sentences in message 102 and a reduction ratio of compression algorithm is less than the quantity of the multiple number of bits in code 114. In at least some embodiments, the processor may determine that the semantic richness of message 102 is sufficient to carry code 114 by comparing code 114 to the sequence of binary bits and determining that the multiple numbers of bits of code 114 can be represented by a corresponding number of binary bits of the sequence of binary bits. Processing flow 300 may proceed from block 306 to block 308.

[0045] Block 308 (Mark Semantic Sentences to Carry the Code in the Textual Message) may include marking a subset of the multiple semantic sentences to carry the code in the textual message. For example, the processor may mark the subset of the multiple semantic sentences of message 102 such that the binary bit corresponding to each of the marked semantic sentences indicates a respective one of the bits of code 114. In at least some embodiments, the processor may mark the marked semantic sentences by prefixing each of the marked semantic sentences with a label. In at least some other embodiments, the processor may mark the marked semantic sentences by suffixing each of the marked semantic sentences with a label. In still some other embodiments, the processor may mark the marked semantic sentences by highlighting the marked semantic sentences in a way that is recognizable by the receiving party.

[0046] In at least some embodiments, processing flow 300 may further include transmitting the textual message with the code embedded therein. For example, after encoding message 102 with code 114, the processor transmits, or causes the associated computing device to transmit, the encoded message to the receiving party.

[0047] Fig. 4 shows a system 400 that is configured to perform information coding based on semantic data reasoning, arranged in accordance with at least some embodiments described herein.

[0048] Example system 400 may include one or more components, parts or modules as illustrated by one or more of first component 402, second component 404, third component 406, and fourth component 408. Although illustrated as discrete components, various components may be divided into additional components, combined into fewer components, or eliminated, depending on the desired implementation. Further, system 400 may be implemented by software, hardware, or a combination of software and hardware in any type of computing device, such as example computing device 500 to be described below.

[0049] First component 402 may be configured to segment a textual message into a multiple number of semantic sentences. For example, first component 404 may segment message 102 into a multiple number of semantic sentences as M = {s^ s₂, ... s, ...}.

[0050] Second component 404 may be configured to analyze the multiple semantic sentences to generate a sequence of binary bits, with each bit of the sequence of binary bits corresponding to a respective one of the semantic sentences. In at least some embodiments, second component 404 may analyze the multiple semantic sentences and generate a binary 0 when a concept conveyed by a respective one of the semantic sentences is false based on information in a knowledge base, such as first knowledge base 116. Conversely, second component 404 may generate a binary 1 when the concept conveyed by the respective one of the semantic sentences is true based on the information in the knowledge base.

[0051] Third component 406 may be configured to determine whether the textual message is suitable to carry a code of a multiple number of bits therein. In at least some embodiments, third component 406 may determine that message 102 is suitable to carry code 114 when third component 406 determines that a length of message 102 is suitable to carry code 114 and that semantic richness of message 102 is sufficient to carry code 114. In at least some embodiments, third component 406 may determine that the length of message 102 is suitable to carry code 114 based on a number of factors. Such factors may include, for example: (1) a quantity of the multiple number of semantic sentences in message 102, (2) a quantity of the multiple number of bits in code 114, and (3) that a sum of a redundancy number and a product of the quantity of the multiple number of semantic sentences in message 102 and a reduction ratio of compression algorithm is less than the quantity of the multiple number of bits in code 114. In at least some embodiments, third component 406 may determine that the semantic richness of message 102 is sufficient to carry code 114 by comparing code 114 to the sequence of binary bits and determining that the multiple numbers of bits of code 114 can be represented by a corresponding number of binary bits of the sequence of binary bits.

[0052] Fourth component 408 may be configured to mark a subset of the multiple semantic sentences to carry the code in the textual message in response to a positive determination that the textual message is suitable to carry a code of a multiple number of bits therein. In at least some embodiments, fourth component 408 may mark a subset of the multiple semantic sentences to carry code 114 in message 102 by marking the subset of the multiple semantic sentences such that the binary bit corresponding to each of the marked semantic sentences indicates a respective one of the bits of code 114. In at least some embodiments, fourth component 408 may mark the marked semantic sentences by prefixing each of the marked semantic sentences with a label. In at least some other embodiments, fourth component 408 may mark the marked semantic sentences by suffixing each of the marked semantic sentences with a label. In still some other embodiments, fourth component 408 may mark the marked semantic sentences by highlighting the marked semantic sentences in a way that is recognizable by the receiving party.

[0053] In at least some embodiments, system 400 may further include fifth component 410 that may be configured to transmit the textual message with the subset of the multiple number of semantic sentences being marked. For example, fifth component 410 may transmit the encoded message to the receiving party that has access to first knowledge base 116 or has second knowledge base 118 which is a duplicate copy of first base 116.

[0054] Embodiments of the proposed technique advantageously provide an additional layer of security as well as efficiency in data communication. Further, the proposed technique offers many applications in a cloud-computing environment such as data classification, authentication and PRI management.
