Description

Encrypted distribution file transfer system

The present invention relates to a data transmission system, especially a transmission system for distributing files.

A will is an act performed by the deceased during his lifetime and becomes effective when he dies. The person who writes the will can freely dispose of his property with the will, provided that the special points are not violated. There are five types of wills stipulated by law: self-written will, notarized will, sealed will, ghost written will, and oral will.

Traditionally, the making of a will is usually written in writing to write down the wealth that you want to distribute. However, when the deceased dies, the heir must still provide various documents such as death certificate, movable property certificate, real estate title, etc. In terms of the procedures of these documents, not only the work is cumbersome, but also the disputes of the heirs are often extended, and the authenticity of the property documents is even questioned, which further derives disputes over inheritance. Even if the current technology is able to digitize the will, this method does not guarantee that the digitized information can be traced back to the past, nor can it ensure that the digitized will is intercepted and tampered with by interested parties during the transmission of the digital will on the Internet. On the whole, there is still a lack of a system that efficiently integrates the formation of wills to the distribution of estates among agencies.

In view of this, the present invention proposes a distributed file transmission system to solve the above-mentioned problems.

Please refer to Figure 1. The platform 50 includes a plurality of processing nodes 51, 52, ..., 59 that are communicatively connected to each other. The communication connection between the processing nodes is, for example, exchanging data through a wired network or a wireless network, which is not limited by the present invention. Each processing node can execute a consensus algorithm and a verification algorithm.

The consensus algorithm generates a nonce randomly so that the hash value obtained by combining the temporary value and data with the one-way hash function operation is smaller than a dynamically adjustable difficulty target value (Difficulty Target). The one-way hash function is, for example, MD5, SHA-256, SHA-512, or Hashcash. In practice, consensus algorithms such as Proof of Work (PoW), Proof of Stake (PoS), Delegated Proof of Stake (DPoS) or Proof of Capacity (PoC) And other mechanisms.

The verification algorithm verifies whether the hash value in the data sent by other processing nodes to this processing node is legal, thereby determining whether to allow this data to be written into the existing data string.

In practice, the first input device 12 is, for example, a camera, a video camera, a scanner, a tape recorder, any hardware device that can digitize a text will or an oral will, which is not limited by the present invention. The distribution document refers to the will, which records the way the deceased’s property is distributed to the heirs, and records the signatures of all witnesses. Proof documents, such as the passbook of the deceased or financial proofs such as the land and house title, are used to prove that the distributed property really belongs to the deceased.

Please refer to Figure 1. The first processing device 14 is electrically connected to the first input device 12. In one embodiment, the first processing device 14 converts the distribution file and the certification file obtained by the first input device 12 into the original distribution file, and controls the first communication device 16 to upload the original distribution file to the platform 50. Specifically, the first processing device 14 uploads the text will and property certification documents of the deceased to the platform 50 for retention. Since the original distribution file needs to pass the consensus and verification of one or more of the multiple computing nodes on the platform 50 before it can be written, the original distribution file that is allowed to be written has the property that it cannot be tampered with.

In another embodiment, the first processing device 14 can determine a distribution quantity of the distribution file and one distribution object corresponding to the distribution quantity, wherein each distribution object has an identification code. The first processing device 14 converts the distribution document and the certification document corresponding to the distribution object into one or more sub-distribution files according to the distribution quantity. In practice, the first processing device 14 can run an Optical Character Recognition (OCR) algorithm to identify the number of heirs (distributed objects) in the will (distributed quantity) and the amount of inheritance allocated to each heir. Each heir has an ID number. The first processing device 14 divides the original will into several files according to each heir and the corresponding allocation quota and then converts them separately. For example, if the original will is a distribution document stating that "the spouse can get a bank deposit of 20 million, the eldest son can get a house worth 30 million, and the eldest daughter can get a land worth 50 million." Then the content of the first sub-distribution file contains the text stating "Spouse gets 20 million" and the digitized bankbook A, and the content of the second sub-distribution file contains the text and figures stating "The eldest son gets 30 million" The contents of the converted house deed and the third sub-distribution file contain the text of "the eldest daughter gets 50 million" and the digitized land deed. In another embodiment, the first processing device 14 encrypts each sub-distribution file according to the identification code of each heir, where the identification code may be the heir's ID card number or a password customized by the heir.

Please refer to Figure 1. The first communication device 16 is electrically connected to the first processing device 14 and is communicatively connected to the platform 50. The first communication device 16 can send the original distribution file to the platform 50. When the deceased dies in the hospital, the hospital will issue a death certificate and broadcast a death notice to the platform 50 through the first communication device 16.

Please refer to Figure 1. The second server 20 includes: a storage device 22, a second processing device 24 and a second communication device 26. In practice, the second server 20 is, for example, a server set up in a law firm or a notary office.

Please refer to Figure 2. The storage device 22 stores the first encrypted information, the first decrypted information, the second encrypted information, and the second decrypted information. In practice, these encrypted information and decrypted information, for example, use public key cryptography (Public Key Cryptography) public key and private key. Public key encryption algorithms such as RSA (Rivest-Shamir-Adleman) or Elliptic Curve Digital Signature Algorithm (ECDSA), but not limited to this.

The second processing device 24 obtains the original distribution file from the platform 50 through the second communication device 26. In one embodiment, the second processing device 24 uses a public key encryption algorithm to encrypt the part of the original distribution file belonging to the distribution file according to the first encrypted information, and uses the public key to encrypt the part belonging to the certification file according to the second encrypted information. The encryption algorithm performs encryption. The second processing device 24 converts the encrypted original distribution file into an encrypted distribution file, and uploads it to the platform 50 through the second communication device 26. In practice, the entrusted lawyer or notary can obtain the will and property certification documents uploaded by the deceased when he was in the hospital on the platform 50. After verifying that the will meets the legal requirements and the certification documents are all legal originals, the original The distribution file is digitally signed and encrypted and uploaded to the platform 50.

In another embodiment, the second processing device 24 further targets the part of each heir in a single original distribution file (or multiple distribution sub-files) based on the identification code of each heir, the first encrypted information, and the second encrypted information. Encrypted separately. For example, in order to avoid future disputes on inheritance, a lawyer or a notary can independently encrypt the parts of the will belonging to the spouse, eldest son, and eldest daughter into a file according to their respective identification codes.

When the second processing device 24 receives the notification through the second communication device 26, the second processing device 24 controls the second communication device 26 to send the first decryption information and the second decryption information to the platform 50. In other words, when the law firm or notary office knows through the platform 50 that the deceased has died, it needs to initiate the subsequent inheritance process, so the decrypted information is sent to the platform 50.

Please refer to Figure 1. The second communication device 26 is electrically connected to the storage device 22 and the second processing device 24. The second communication device 26 obtains the original distribution file from the platform 50, receives the notification, sends the encrypted distribution file to the platform 50, and sends the first and second decrypted information to the platform 50 according to the instructions of the second processing device 24.

Please refer to Figure 1. The third server 30 includes a third processing device 34 and a third communication device 36. In practice, the third server 30 is, for example, a server set up in the Internal Revenue Service.

The third processing device 34 can convert the encrypted distribution file into the original distribution file according to the first decryption information and the second decryption information, and generate a renewable signal. In practice, the IRS after receiving the first decrypted information and the second decrypted information is equivalent to knowing that the decedent has died. Therefore, the IRS obtains the encrypted will and property certification documents of the decedent from the platform 50 , And use the first decryption information and the second decryption information for decryption. After the deceased has paid the inheritance tax, the IRS can send a renewable signal representing the "tax payment certificate" through the third processing device 34.

The fourth processing device 44 can convert the distributed encrypted file into the original distributed file according to the first decryption information and the second decryption information. The fourth processing device 44 can also execute a verification procedure based on the verification code and the renewable signal to generate a verification signal. The verification procedure also includes checking whether the identification code is consistent with the verification code. In other words, the bank can check whether the heir is the legal heir recorded in the distribution document through the second input device 42, and check whether the heir has paid the inheritance tax, and then execute the distribution procedure according to the content of the distribution document to fulfill the distribution of the estate. The distribution procedure described can be carried out on the Internet or at a physical counter. If it is done on the Internet, the heir can use the natural person certificate to prove his identity on the Internet, and then the bank can perform online transfer based on the amount allocated to the heir as specified in the will. It should be noted that the number of the fourth server 40 of the present invention is not limited. In practice, the fourth server 40 to the platform 50 of multiple banks can be integrated, so that the inconvenience of traveling to and from multiple banks can be saved.

In summary, the distribution file transmission system disclosed in the present invention can enhance the security of distributed files through the establishment of the platform and encryption mechanism, and ensure its authenticity and non-modification, and can be transferred between multiple agencies Integrate will making and inheritance distribution, reducing the inconvenience that heirs need to prepare a large amount of textual materials to travel between various agencies.
