Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first" and "second," and the like in the description and claims of the present invention and the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not set forth for a listed step or element but may include steps or elements not listed.
In the embodiment of the invention, a digital currency address tamper-proofing method is provided, and digital currency is alternative currency in the form of electronic currency, which can be understood as virtual currency based on a node network and a digital encryption algorithm. The virtual currency comprises special currency such as game currency, Q point and the like and bit currency Etfang digital encryption currency. When the money is transacted, the digital money address of the digital electronic purse needs to be input for transferring and the like. Specifically, the method may comprise the steps of:
s101, when the operation of copying the digital currency address is monitored, the digital currency address in the target clipboard is obtained.
Since the digital money address corresponding to the digital wallet is generally composed of irregular numbers and letters, the user may copy the digital money address to a preset place such as a clipboard or a memo for use, and then copy the address from the clipboard when using. When the fact that the user operates the digital currency address in the clipboard is monitored, namely the digital currency address is copied from the clipboard, the controller can firstly acquire the digital currency address in the target clipboard instead of directly performing subsequent step operation on the digital currency address in the clipboard, and the purpose of doing so is that the content stored in the clipboard of the user cannot be changed, and other threads are prevented from being influenced.
And S102, judging to obtain the digital currency type according to the digital currency address.
After the digital currency address is acquired, the type of the digital currency is judged according to the composition structure of the digital currency address, and usually, identification information indicating the type of the digital currency address exists in the digital currency address, and the type of the digital currency is acquired through the identification information. Specifically, the identification information may be represented by the initial letter and the character string length, that is, it may be determined which type of digital money the current digital money address belongs to, from the initial letter and the character string length of the character string of the acquired digital money address.
S103, determining a first character string and a second character string according to the digital currency type and the corresponding length of the digital currency address.
And S104, copying the first character string to a target position, and generating prompt information.
Since the digital currency address copied by the user is completed in a segmented mode during pasting in the embodiment of the application, a first character string and a second character string need to be determined firstly, wherein the first character string is used for directly copying to a target position, and the second character string needs to be manually input by the user.
And the lengths of the corresponding first and second character strings may be determined according to the type of the numeric currency and the actual length of the numeric currency address. In order to facilitate manual input of the user, the second character string is usually set to be 6 characters, and of course, the length of the second character string may be flexibly set according to the use habit of the user, that is, the length of the second character string is set according to the input habit of the user. The first string is copied directly to the target location, which may be a dialog box that requires entry of a digital currency address or an address bar of a digital wallet. And generating prompt information while copying the first character string to the target position so as to prompt the user to input the remaining second character string.
The invention provides a digital currency address tamper-proof method, which limits the length of a digital currency address copied and pasted by a user and prompts the user to manually input character strings of part of the digital currency address, so that a hacker can lose the behavior of modifying the digital currency address by hijacking the content of a clipboard, the hacker can hijack the clipboard to lose significance, and the safety of the digital currency of the user is protected.
On the basis of the above embodiment, when determining the first character string and the second character string, the method of the embodiment of the present invention specifically includes:
s201, copying the digital currency address to a specified memory location;
s202, determining a second character string according to the digital currency type;
s203, deleting the second character string from the digital currency address of the specified memory location to obtain a first character string.
Firstly, the digital currency address is copied to a specified memory location, it should be noted that the memory location is a memory different from the memory location of the clipboard, so that the character strings corresponding to the digital currency address can be conveniently operated, for example, the first character string can be obtained after deleting some character strings. For example, the method provided by the embodiment of the invention generates a wallet plug-in, applies the wallet plug-in to the field of digital currency, copies the digital currency address to the plug-in memory for erasing when it is monitored that the user copies the digital currency address, and then pastes the erased content into the address input field directly from the plug-in memory, so that the content of the memory of the clipboard is not changed, and the influence on other threads is prevented. For example, when the wallet runs in the background and the user wants to write a text document, a bitcoin address is copied, the content in the clipboard memory is not erased, and the content in the wallet plug-in memory is erased 6 bits later. At the moment, the transfer operation is carried out to read the content from the plug-in memory, namely the content after being erased; at this time, text editing is performed, namely, the content is read from the memory of the clipboard and is the copied original content.
Different digital currencies have different formats of digital currency address. It can be judged which type of currency the address on the current clipboard belongs to from the beginning letters of the acquired character string and the character string length, for example, bitcoin always starts with "1" or "3" and is generally 34 bits in length, etherhouse always starts with "0 x" and is 40 bits in length, and ledebut coin always starts with "L" and is 34 bits in length. When the data on the clipboard starts with '1', the data is judged to be the bitcoin address, when the data on the clipboard starts with '0 x', the data is judged to be the Ethengfang address, and other currency addresses are judged in the same way. The format of a common currency address is shown in table 1.
TABLE 1
On the basis of the above embodiment, the method further includes:
judging whether the address length of the digital currency is consistent with the standard address length corresponding to the digital currency type, and if so, determining a first character string and a second character string;
if not, judging whether the length of the digital currency address is smaller than the standard length of the digital address, and if so, determining the digital currency address as a first character string.
It should be noted that when it is monitored that the user copies the digital currency address on the clipboard, it is first determined whether the length of the copied digital currency address is consistent with the standard length L of the corresponding type, if so, it is verified that the user has made all copies, and then the first character string and the second character string are determined in order to ensure security. If the length is less than the standard length, the user is certified that the user partially copies at the time of copying, and the copied numeric currency address is taken as a first character string. For example, if the length of the second character string is set to 6, after the content copied on the clipboard is confirmed to be of a certain currency type, the length L of the character string on the clipboard is calculated, the value of L is compared with the value of L-6, if L is larger than or equal to L-6, the character string in the plug-in memory is subjected to six-bit erasing processing, and when a user performs a pasting operation, the erased content is directly pasted to the wallet address bar from the plug-in memory, and the user is reminded to 'please manually input six bits later'.
It should be noted that, in order to facilitate the operation of the user, the method in the embodiment of the present invention further includes:
and acquiring setting information, and determining the length of the second character string according to the setting information, wherein the setting information comprises configuration information automatically generated according to the digital currency type or configuration information set by a user.
That is, the length of the second character string may be automatically determined according to the length of the numeric currency address of the type, or may be determined based on information set by the user, that is, if the user does not set the length of the input character string, a default length is adopted as the length of the second character string. For example, the length of the second string is set to 6 bits. The bit coin wallet address is typically 34 bits, so the length that the user can copy and paste is 28 bits; the ether house wallet address is typically 40 bits, then the length that the user can copy and paste is 34 bits.
If the first string is set to the same length, then the currency with the longer address would need to be manually entered too much. For example, if the length of the copy and paste is set to be 28 bits according to the standard of bitcoin, 12 bits need to be manually input when the user performs the ether house wallet transfer, and the input is too long, which causes unnecessary troubles and is easy to make mistakes.
It should be noted that the above is directed to a multifunctional integrated wallet, which can transfer multiple currencies at the same time. But may be set to a fixed length if for a particular wallet, such as a bitcoin-only wallet, or an etherhouse-only wallet.
The invention limits the length which can be copied and pasted by judging the content copied by the user to determine the currency type, and the user has to manually input six digits, and the length is as long as the six-digit key password of the bank, so that the invention is safe; when a hacker hijacks the clipboard and writes the address of the hacker, the hacker can not obtain any benefit because the last six bits of the address of the hacker are erased and replaced by the new last six bits manually input by the user, and the new address is not the address of the hacker any more, and the hacker has lost significance in carrying out the clipboard hijack at the moment, so that the clipboard hijack can be fundamentally prevented.
Correspondingly, in another embodiment of the present invention, there is also provided a digital currency address tamper-proofing system, see fig. 2, comprising:
an acquisition unit 10 configured to acquire a digital money address in a target clipboard when an operation of copying the digital money address is monitored;
