[0024] In order to further elaborate on the technical means and effects adopted by the present invention to achieve the intended invention purpose, the following will, in combination with the accompanying drawings and preferred embodiments, elaborate in detail on a method for extracting virtual currency wallet addresses proposed according to the present invention, its specific implementation manner, structure, features and effects. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures or characteristics in one or more embodiments can be combined in any suitable form.

[0025] Among them, in the description of the embodiments of the present invention, unless otherwise specified, " / " means "or". For example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present invention, "a plurality" means two or more than two.

[0026] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as implying or suggesting relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs.

[0028] In the related art, different types of virtual currency wallet addresses usually have specific formats and features. For example, the wallet address of Bitcoin is generally a string composed of numbers and letters (case-sensitive), usually between 26 and 35 characters in length, and often starts with "1", "3" or "bc1". The regular expression rules are: (1|3)[1-9A-HJ-NP-Za-km-z]{26,33} and

[0029] bc1[0-9A-Za-z]{11,72}. The wallet address of Ethereum is a string composed of 40 hexadecimal characters, starting with "0x", and the regular expression rule is (0x|0X)[0-9a-fA-F]{40}. By using the efficient text matching tool of regular expressions, it is possible to quickly locate possible wallet addresses in a large amount of data. Compared with the traditional search method that relies on manual checking one by one, it shows a relatively significant advantage in work efficiency, but there are still problems with recognition accuracy. The high false recognition rate leads to a large number of invalid wallet addresses being mined, interfering with the case handlers.

[0030] Based on this, an embodiment of the present invention provides a method for extracting virtual currency wallet addresses. Through text extraction, text preprocessing, address type recognition and verification, and result sorting module processing, the mining efficiency, wallet address accuracy, integrity, and scalability are significantly improved.

[0031] The following specifically describes the specific solution of a method for extracting virtual currency wallet addresses provided by the present invention in conjunction with the accompanying drawings. Please refer to Figure 1 , which shows a schematic diagram of the implementation process of a method for extracting virtual currency wallet addresses provided by an embodiment of the present invention. The method includes:

[0032] 101. Obtain the source information of the wallet addresses of various virtual currencies.

[0033] Here, in the virtual currency trading scenario, obtain the source information of the wallet addresses of various virtual currencies. The virtual currency trading scenario can be any type of virtual currency trading; among them, various virtual currencies are various different cryptocurrencies, including: Bitcoin, Ethereum, Tron, etc. The source information of the wallet addresses of various virtual currencies can include multiple aspects, such as virtual currency-related application programs (APPs), personal computer (PC) programs, chat records in chat software, multimedia files such as photo albums and screenshots, and so on.

[0034] 102. Perform text processing on the source information to obtain the processed text.

[0035] Here, by performing text extraction on the source information and preprocessing the extracted text, the processed text is obtained.

[0036] In some possible implementation manners, the above step 102 can be implemented through the following steps 121 and 122 (not shown in the figure):

[0037] 121. Perform text extraction on the various virtual currencies to obtain the extracted text.

[0038] Here, since the sources of wallet addresses are diverse and their forms are various, it is necessary to perform unified text extraction and processing on the source information of wallet addresses. The specific processing logic is as follows:

[0039] Take evidence of virtual currency-related APPs and PC programs, extract all valid fields in the structured forensic result data, and concatenate all fields in each record into a single piece of plain text.

[0040] Use the detection document tool (Apache Tika) to implement the document content parsing function, extract the body content of all document files, and convert it into plain text; and use Optical Character Recognition (OCR) technology to extract the text in all types of pictures (such as.jpg,.png,.bmp,.tiff), including pictures from Office and PDF, and convert it into plain text, so as to obtain the extracted text.

[0041] 122. Perform text preprocessing on the extracted text to obtain the processed text.

[0042] Here, the extracted text can be preprocessed by a combination method of regular expressions and length filtering to reduce the amount of data for subsequent verification and obtain more accurate processed text.

[0043] In some possible implementation manners, first use the regular expression matching the extracted text to perform regularization processing on the extracted text to obtain the regularized text; then use the length filtering function to filter the string length of the regularized text to obtain the processed text. Here, to quickly and accurately screen out potential wallet addresses from a large amount of text, a combination method of regular expressions and length filtering is used to preprocess the extracted text, thereby reducing the amount of data for subsequent verification. The algorithm is C(t) = R(t) ∩ L(t); where C(t) is the set of potential wallet addresses after filtering, and R(t) is the regular expression matching function. Since wallet addresses are composed of letters and numbers, regular expressions can be used to match possible address strings. The regular expression rule adopted is: \w*[a-zA-Z]\w*\d\w*|\w*\d\w*[a-zA-Z]\w*. The logic of this regular expression is to accurately identify those strings that must contain both letters and numbers. Specifically, \w in the expression means to match zero or more word characters (including letters and numbers), [a-zA-Z] clearly specifies the range of letters to be matched, and \d is used to match numbers. Through the combined use of the two matching modes (\w[a-zA-Z]\w*\d\w and \w\d\w*[a-zA-Z]\w*) of this regular expression, potential wallet address strings that meet the requirements can be comprehensively and accurately captured.

[0044] L(t) represents the length filtering function, L(t) = {s|s∈Σ, 20≤|s|≤62}. Based on the common length range characteristics of virtual currency wallet addresses, strict length filtering conditions are set to further narrow the screening range. That is, strings with a length less than 20 and strings with a length greater than 62 are filtered out. Through such a length screening mechanism, strings that obviously do not meet the conventional length of wallet addresses can be excluded in advance, thereby greatly reducing the amount of data that needs to be verified later, thereby improving the efficiency and accuracy of the entire wallet address mining process.

[0045] 103, performing address verification on the processed text to obtain verification results of the various types of virtual currencies.

[0046] Here, by performing address identification and verification on the processed text, verification results of various virtual currencies are obtained. In some possible implementations, the above step 103 can be performed by Figure 2 The steps shown achieve:

[0047] 201, performing character verification on the processed text to obtain a character verification result.

[0048] Here, by performing a string prefix check, a string length judgment, an encoding method check, etc. on the processed text, a character check of the processed text is implemented to obtain a character check result. In some possible implementations, the above step 201 can be implemented by the following steps 211 to 213 (not shown):

[0049] 211, obtain a preset string prefix and a preset string length.

[0050] Here, the string prefix of the processed text is checked, and its valid prefix should be "1" or "3", and the string length should be greater than 26 and less than 35. That is, the preset string prefix is ​​"1" or "3", and the preset string length is greater than 26 and less than 35.

[0051] 212 , based on the preset string prefix and the preset string length, respectively verify the string prefix and the string length of the processed text to obtain a first verification result.

[0052] Here, it is determined whether the string prefix of the processed text is a preset string prefix, and whether the string length of the processed text satisfies the preset string length, thereby obtaining a first verification result.

[0053] 213, perform encoding attribute verification on the character string of the processed text to obtain a second verification result.

[0054] Among them, the character verification result includes the first verification result and the second verification result. The Legacy / P2SH type address uses Base58 encoding, so the string does not contain the number 0 (zero), the uppercase letter O, the lowercase letter l (the lowercase form of L), and the uppercase letter I. Based on this, it is determined whether the string of the processed text meets this encoding to obtain the second verification result. In this way, by verifying the string prefix, string length, and encoding attributes of the processed text, the character verification of the processed text can be more accurately implemented to obtain a relatively rich character verification result.

[0055] 202. Perform a hash verification on the processed text to obtain an initial verification result.

[0056] Here, by using the public key hash and the initial checksum, the hash verification of the processed text is implemented to obtain the initial verification result. In some possible implementation manners, the above step 202 can be implemented through the following steps 221 and 222 (not shown in the figure):

[0057] 221. Perform a character encoding check on the processed file to obtain the public key hash and the initial checksum.

[0058] Here, the Base58 decoding is performed on the string address of the processed file, and it is converted into the corresponding byte value according to the character mapping table, and the original byte data sequence is gradually restored. The original byte sequence mainly consists of two parts: the public key hash + the trailing 4-byte checksum. The public key hash is denoted as E, and the trailing 4-byte checksum is denoted as F.

[0059] 222. Based on the public key hash and the initial checksum, perform a hash verification on the processed text to obtain the initial verification result.

[0060] Here, by using the public key hash as the input, two hash operations are performed to obtain the candidate checksum, and the candidate checksum is compared with the initial checksum to obtain the initial verification result. In some possible implementation manners, the above step 222 can be implemented through the following process:

[0061] First, perform a first hash operation on the public key hash to obtain an initial hash value. Second, perform a hash operation on the initial hash value to obtain a candidate hash value. Third, select a preset byte from the candidate hash value to obtain the candidate checksum. Finally, compare the initial checksum with the candidate checksum to obtain the initial verification result. In this way, two hash operations are performed based on the public key hash to obtain the candidate checksum, so as to compare the initial checksum with the candidate checksum to obtain a relatively accurate initial verification result.

[0062] Here, the public key hash E is taken as the input, and the first SHA256 hash operation is performed to obtain a 256-bit hash value G 1 = SHA256(E) (i.e., the initial hash value); then, the initial hash value is taken as the input again, and the second SHA256 hash operation is performed to obtain another 256-bit hash value G 1 = SHA256(G 2 )(i.e., the candidate hash value). The first 4 bytes are taken from the hash value G 2 obtained from the second SHA256 operation and denoted as H. These 4 bytes are the calculated checksum (i.e., the candidate checksum). If the initial check result indicates that F = H, it means that the candidate checksum verification passes, and the string is a valid BTC address. In this way, by combining the public key hash and the initial checksum, hash verification is performed on the processed text, thereby improving the accuracy of the initial check result.

[0063] 203, the character check result and the initial check result are fused to obtain the check results of various virtual currencies.

[0064] Here, for different types of virtual currencies, the first check result, the second check result, and the initial check result of various virtual currencies are combined to obtain a combined result; if the combined result indicates that at least one type of virtual currency among various virtual currencies passes the check, then it is determined that the check result is a pass. Here, since different types of cryptocurrencies each have unique wallet address formats and rules, the corresponding check algorithms also vary. To achieve comprehensive identification and verification of wallet addresses of multiple cryptocurrencies, an embodiment of the present invention constructs a general address identification and verification phase framework, expressed as: V(a) = ∨(Vi(a)), i ∈ {BTC, ETH, TRX,...}; where V(a) represents the overall verification result of any given wallet address a, which is obtained by performing a logical OR (∨) operation on the respective verification functions Vi(a) of various different cryptocurrencies (such as Bitcoin BTC, Ethereum ETH, Troncoin RTX, etc.). This means that as long as the verification function result of one cryptocurrency is true, the overall address verification can be regarded as passing.

[0065] For any type of virtual currency, obtain the first verification result, the second verification result, and the initial verification result of the any type of virtual currency; if the first verification result, the second verification result, and the initial verification result of the any type of virtual currency all pass the verification, determine that the verification result of the any type of virtual currency is verification passed. Here, for each cryptocurrency, its verification function is further refined as: Vi(a) = Pi(a) ∧ Hi(a) ∧ Ci(a), where Pi(a) represents the first verification result, which is mainly responsible for verifying identification features such as specific prefixes of wallet addresses to determine whether the address meets the format requirements of the cryptocurrency; Hi(a) represents the second verification result, which focuses on checking a certain specific attribute of the address (such as encoding method, case rules, etc.); Ci(a) represents the initial verification result, which involves a more core verification algorithm for verifying the integrity and validity of the address to ensure that the address can be used normally in the cryptocurrency system and has not been tampered with; the three functions perform a logical AND (∧) operation to obtain the final result.

[0066] Through the above steps 201 to 203, by performing character verification and hash verification on the processed text, it is possible to more comprehensively and accurately implement the verification of different types of virtual currencies.

[0067] 104. Based on the verification results of the various types of virtual currencies, determine the target wallet addresses of the various types of virtual currencies.

[0068] Here, first obtain the financial-related information of each wallet address; among them, the financial-related information includes: the balance of the wallet address, transaction records, transfers in, transfers out, the most recent transaction time, and other information. Then, perform a combined statistics on the verification results of the various types of virtual currencies to obtain the number of occurrences of each wallet address and the identification information of the original data where each wallet address appears; here, the wallet addresses are from the forensics results and evidence files, and it is necessary to perform a combined statistics on the results to calculate the number of occurrences of each wallet address and record the id of the original data where each wallet address appears in order to implement the traceability function. Finally, based on the financial-related information, the number of occurrences, and the identification information, identify the target wallet addresses. Here, simultaneously call the API interface of the blockchain analysis platform to query the balance of the wallet address, transaction records, transfers in, transfers out, the most recent transaction time, and other information, so as to assist the case-handling personnel to quickly analyze and identify the key wallet addresses. In a specific example, apply the method of extracting virtual currency wallet addresses to a specific product, and obtain Figure 3The displayed interface, where area 31 presents the recognition result categories, including: entity recognition, image recognition, virtual currency (and wallet address), and clue focusing, etc.; area 32 presents the detailed content of each wallet address. Thus, the method for extracting virtual currency wallet addresses provided by the embodiments of the present invention can well mine the wallet addresses in structured forensic result data and unstructured files, and query the wallet address transaction information, which can provide further analysis ideas and breakthrough points for analysts, greatly improving the work efficiency of forensic analysis, providing an important idea for other similar forensic and analysis products, and will be widely applied in the field of electronic data forensic analysis.

[0069] In the embodiments of the present invention, after obtaining various virtual currencies in the virtual currency transaction scenario, the obtained text is processed through text processing of the various virtual currencies; in this way, through text processing of the various virtual currencies, the obtained processed text can be made convenient for address verification. Then, through address verification of the processed text, the verification results of the various virtual currencies are obtained, and according to the verification results of the various virtual currencies, the target wallet addresses of the various virtual currencies are determined. In this way, through text processing of the various virtual currencies and address verification of the processed text, the target wallet addresses of the various virtual currencies can be more accurately identified, thereby improving the mining efficiency and accuracy of the wallet addresses of the various virtual currencies.
