The number of nodes in the process of authentication refers to the number of nodes in the process of authentication of a file or document, for example: the process authentication node may be a process authentication node for drafting, submitting, reviewing, retuning, returning, publishing, etc. Since the color of a general electronic stamp is red, the standard RGB value may be (255, 0). The node RGB value set refers to the RGB value set after the standard RGB value is split.
In the embodiment of the present invention, splitting the preset standard RGB value into the node RGB value set according to the process authentication node number includes:

And randomly distributing the single quantitative analysis value set to the flow authentication node set to obtain the node RGB value set.
The RGB value splitting number means the number of the standard RGB values split into node RGB values. The single quantization color value refers to a single color value in the standard RGB values, for example: when the standard RGB values may be (255, 0), the single quantized color values refer to 255,0, and 0. The single quantized split value set refers to a split value set obtained by splitting the single quantized color value, for example: when the single quantized color value is 255 and the number of flow authentication nodes is 6, the single quantized split value set may be 50, 30, 40, 37, 20, 78; when the single quantized color value is 0 and the number of flow authentication nodes is 6, the single quantized split value set is 0, 0.
S2, encrypting the node RGB value set and randomly distributing the node RGB value set to a pre-constructed flow authentication node set to obtain an exclusive authentication RGB value corresponding to each flow authentication node.
Further, the encryption manner of the node RGB value may be an existing encryption manner, and the encryption level is determined according to the security level, which is not described herein.

S3, acquiring a text to be authenticated, and receiving a logic electronic seal authenticated on the text to be authenticated by a first authentication node in the process authentication node set according to the corresponding exclusive authentication RGB value to obtain a first authentication text.
It can be understood that the logic electronic seal refers to the electronic seal which performs authentication according to the exclusive authentication RGB value of the corresponding flow authentication node and the preset random seal deflection angle. The random seal deflection angle refers to the deflection angle of the logic electronic seal and the aligned electronic seal, and in the process of manual seal, the skew of the seal may exist, so that the skew seal exists.
In the embodiment of the present invention, the obtaining, by the first authentication node in the receiving process authentication node set, a first authentication text according to a logical electronic seal authenticated on the text to be authenticated by a corresponding proprietary authentication RGB value includes:
acquiring a logic electronic seal of the first authentication node;

And receiving a logic electronic seal authenticated by the user on the control text to be authenticated according to the corresponding exclusive authentication RGB value at the first authentication node to obtain a first authentication text.
Further, when the logic electronic seal is embedded into the text to be authenticated, the logic electronic seal is not embedded in an odd positive way, the manual seal can be imitated, and the authentication is performed when a seal deflection angle exists in a certain range. The seal angle of deflection may range from (0 degrees to 90 degrees). The seal deflection angle refers to the angle between the vertical forward direction of the logic electronic seal and the vertical direction of the text to be authenticated.
S4, acquiring a zero degree reference standard point, calculating a reference authentication angle of the logic electronic seal in the first authentication text according to the zero degree reference standard point, and encrypting the reference authentication angle to obtain an encryption authentication angle.
It can be understood that the zero degree reference mark point refers to an intersection point of a ray, of which the center of the outer ring of the logic electronic seal points to the vertical direction of the text to be authenticated, and the circumference of the outer ring. The reference authentication angle refers to a deflection angle between the numerical forward direction of the logic electronic seal and the vertical forward direction of the text to be authenticated.
In an embodiment of the present invention, the obtaining the zero degree reference point includes:
Identifying a logical electronic seal in the first authentication text;
confirming an outer ring circumference of the logical electronic seal;
identifying zero-degree reference punctuation on the circumference of the outer ring according to a preset zero-degree punctuation confirmation method;
it can be understood that the zero degree punctuation confirmation method refers to a method for determining the position of the zero degree reference punctuation, and the zero degree reference punctuation can be obtained by taking a ray which is used as the center of an outer ring of a logic electronic seal and points to the vertical direction of the text to be authenticated, and extracting the intersection point of the ray and the circumference of the outer ring.
In the embodiment of the present invention, the calculating the reference authentication angle of the logical electronic seal in the first authentication text according to the zero degree reference mark point includes:
identifying a forward punctuation on the outer circumference of the logical electronic seal in the first authentication text;
determining the outer ring circle center of the outer ring circumference of the logic electronic seal;
connecting the circle center of the outer ring with the zero-degree reference mark point to obtain a seal zero-degree mark;
connecting the forward punctuation with the center of the outer ring to obtain a seal reference marking;
and calculating the marking angle of the reference marking of the stamp according to a preset direction by taking the zero marking of the stamp as a zero scale line, so as to obtain the reference authentication angle.
It is understood that the forward punctuation points refer to the intersection points of the ray of the outer ring circle center of the logical electronic seal, which points to the seal positive direction of the logical electronic seal, and the outer ring circle.
In detail, the encrypting the reference authentication angle to obtain an encrypted authentication angle includes:
acquiring an encrypted public key of the second authentication node;
and carrying out public key encryption on the reference authentication angle by utilizing the encryption public key of the second authentication node to obtain an encryption authentication angle.
It can be understood that the encryption method with reference to the authentication angle can be a public key cryptosystem; in this regime, user a has a pair of keys: encryption key (public key)And decryption key (private key)The two are different and no decryption key (private key) can be deduced from the encryption key (public key). If B wants to send encryption information to A, it needs to look up A's encryption key (public key) in the public directoryThe message is encrypted by it, after A receives the ciphertext, it uses its own decryption key (private key)The ciphertext is decrypted. The public key cryptosystem is made in the prior art, and is not described herein. Since the reference authentication angle is an angle value of deflection of the electronic stamp, for example: 5 。 Thus, an encryption effect can be achieved.
In detail, the first authentication node has an encryption public key of the second authentication node, the second authentication node has an encryption public key of the third flow authentication node, and the like, and finally each flow authentication node decrypts the forwarded encryption authentication angle by means of the own decryption private key, so that an iterative decryption function is realized.
S5, identifying a second authentication node in the flow authentication node set, sending the first authentication text and the encryption authentication angle to the second authentication node, and decrypting the encryption authentication angle by using a decryption private key of the second authentication node to obtain a decryption authentication angle.
And S6, performing iterative seal authentication on the first authentication text by using the second authentication node according to the decryption authentication angle and the corresponding exclusive authentication RGB value to obtain an iterative authentication text.
Further, the iterative seal authentication means that the next flow authentication node is used for continuing to authenticate the seal of the forwarded text to be authenticated, decryption is needed in the authentication process to obtain the reference authentication angle, iterative seal authentication is carried out according to the self-exclusive authentication RGB value, and then the authentication is forwarded to the next flow authentication node.
In the embodiment of the present invention, the performing iterative seal authentication on the first authentication text by using the second authentication node according to the decryption authentication angle and the corresponding proprietary authentication RGB value to obtain an iterative authentication text includes:
acquiring the stamp shape of the logic electronic stamp;
constructing a second exclusive authentication seal according to the seal shape by utilizing the exclusive authentication RGB value corresponding to the second authentication node;
according to the logic electronic seal on the first authentication text, the second exclusive authentication seal is overlapped and normalized on the first authentication text, and a second authentication seal to be rotated is obtained;
and rotating the initial to-be-rotated second authentication seal according to the decryption authentication angle to obtain the iterative authentication text.
It can be understood that the registration and normalization means that the second exclusive authentication seal is overlapped with the outer ring circumference of the logic electronic seal (which can be called as the first exclusive authentication seal) on the first authentication text, so that only the angle difference exists between the two seals, then the second exclusive authentication seal is normalized (the positive punctuation of the second exclusive authentication seal is overlapped with the zero reference punctuation), and finally the skew angles of the two seals are controlled to be identical through the decryption authentication angle, thereby realizing superposition on RGB values.
In the embodiment of the present invention, the performing, according to the logical electronic seal on the first authentication text, the superposition and normalization of the second exclusive authentication seal on the first authentication text to obtain the second authentication seal to be rotated includes:
taking the logic electronic seal on the first authentication text as a first exclusive authentication seal;
identifying an outer ring circumferential position of the first proprietary authentication seal;
acquiring the outer ring circumference of the second exclusive authentication seal, and superposing the second exclusive authentication seal on the first exclusive authentication seal according to the outer ring circumference and the outer ring circumference position of the second exclusive authentication seal to obtain an initial second authentication seal;
identifying zero degree reference punctuation and forward punctuation of the initial second authentication seal;
and normalizing the forward punctuation of the initial second authentication seal to the zero-degree reference punctuation to obtain the second authentication seal to be rotated.
And S7, identifying an iteration authentication node set of the second authentication node, executing iteration authentication on the iteration authentication text by using the iteration authentication node set, and updating the iteration authentication node set and the iteration authentication text.
It can be understood that, because the number of the flow authentication nodes may be greater than 2, iteration authentication needs to be repeated circularly, and the iteration authentication node set and the iteration authentication text are updated in real time during the process of iteration authentication, so that the update of the authentication seal is realized.
Further, the iterative authentication node set refers to a subsequent authentication node set of the second authentication node, for example: when the second authentication node is a submitting node, the iterative authentication node set may be a review, returnal, loopback, and publish process authentication node. After the second authentication node completes the seal authentication, the subsequent node needs to continue to perform the seal authentication in an iteration manner, so that the iteration authentication node set and the iteration authentication text need to be updated continuously, for example: after the second authentication node (submitting node) completes the seal authentication, the iteration authentication node set (submitting, reviewing, approving, returning and issuing nodes) and the iteration authentication text (including the electronic seal after the electronic seal of the first authentication node and the second authentication node) of the first authentication node (drafting node) need to be updated by utilizing the iteration authentication node set (reviewing, approving, returning and issuing nodes of the submitting node) and the iteration authentication text (including the electronic seal of the first authentication node only) until the seal authentication of the final node is completed.
S8, judging whether the iterative authentication text completes authentication or not.
In the embodiment of the present invention, the determining whether the iterative authentication text completes authentication includes:
Extracting an iterative authentication seal from the iterative authentication text;
extracting single quantization splitting sum values of the iterative authentication seal;
judging whether the single quantization split sum value is equal to the single quantization color value or not;
if the single quantization split sum value is not equal to the single quantization color value, the iterative authentication text does not finish authentication;
and if the single quantization split sum value is equal to the single quantization color value, the iterative authentication text completes authentication.
It will be appreciated that when the iterative authentication text completes authentication, the RGB values of the iterative authentication stamps in the iterative authentication text should be (255, 0), which indicates that authentication is complete, and that all logical authentication stamps have completed superimposed authentication.
If the iterative authentication text does not complete the authentication, returning to the step of identifying the iterative authentication node set of the second authentication node;
and if the iterative authentication text completes authentication, executing S9, and performing authentication release on the iterative authentication text to complete flow security authentication of the logic electronic seal.
Compared with the background art, the method comprises the following steps: the present invention mainly realizes the authentication release of iterative authentication texts by authenticating the electronic seal with color and reference authentication angles, before performing color authentication, firstly obtains the number of flow authentication nodes, then splits the preset standard RGB value into node RGB value sets according to the number of the flow authentication nodes, finally encrypts and randomly distributes the node RGB value sets to the pre-constructed flow authentication node sets to obtain the exclusive authentication RGB value corresponding to each flow authentication node, before performing construction of reference authentication angles, firstly obtains a text to be authenticated, receives a first authentication node in the flow authentication node set according to the corresponding exclusive authentication RGB value on the text to be authenticated, and then extracts the reference authentication angles on the first authentication text, when the reference authentication angles are extracted, firstly obtains zero degree reference standard points, calculates the authentication angles of the logic electronic seal in the first authentication text according to the zero degree reference standard RGB value sets, performs encryption and decryption authentication on the first authentication angles, and then performs encryption and decryption authentication on the first authentication text according to the corresponding exclusive authentication RGB value, and then performs encryption and decryption authentication on the second authentication angles, and the first authentication text is encrypted and the second authentication angle is required, and performing iterative seal authentication on the first authentication text by using the second authentication node according to the decryption authentication angle and the corresponding exclusive authentication RGB value to obtain an iterative authentication text, wherein the number of the iterative authentication node sets of the second authentication node is possibly more than two, so that the iterative authentication node sets are required to be identified, the iterative authentication node sets are used for performing iterative authentication on the iterative authentication text, and the iterative authentication node sets and the iterative authentication text are updated, thereby realizing the iterative authentication function, finally judging whether the iterative authentication text is authenticated or not, returning to the step of identifying the iterative authentication node sets of the second authentication node if the iterative authentication text is not authenticated, and performing authentication release on the iterative authentication text if the iterative authentication text is authenticated. Therefore, the flow safety authentication method, the device, the electronic equipment and the computer readable storage medium of the logic electronic seal can solve the problem that the current electronic seal has poor safety protection effect.
