The authenticity of your videos is now undeniable thanks to Prover
Today I will write about an interesting project of interesting people. Ivan Pisarev and Ilya Svirin showed themselves in the Nordavind project , having independently developed hardware-software, very simple and very sophisticated solutions for various fields, from health to safety. And recently, they got an idea ...
Four billion people all over the world own gadgets. The video content they create has long ceased to be used only for entertainment purposes - today it is a necessary part of the media, financial, insurance, legal and medical industries. The “fakes” given out as the truth have led to scandals and even tragedies more than once, so the need for verifying the authenticity of video files is unusually high. Service Prover, confirming the reliability of the video with reference to a specific time and device, was created precisely for this purpose. Prover
technology ensures that the content was recorded at a specific time in a specific place with the camera of a particular device, and confirms the absence of signs of forgery and editing. This was made possible through the use of two leading blockchain platforms: Emercoin and Ethereum . For verification of video materials, Prover offers two methods of verification of video materials. The first is using swype code
. The user who turned on the smartphone’s camera sees the swype code generated in the blockchain - a coordinate grid of 9 points, 3 in a row. To enter it, the user needs to move the phone in space so that the virtual swype line goes along the desired path. After shooting, the hash of the received video file with all data will be automatically saved in Prover.
The second method, which does not require any additional user actions, is to record information from all sensors available in the mobile device: accelerometer, gyroscope, magnetometer, GPS, etc. The mathematical apparatus developed by the Prover team will be able to restore the movement of the mobile device in the user's hands in great detail. and match these movements to video content. A mathematical model of such an apparatus has already been created.
What elements does Prover consist of? Firstly, Prover is a mobile application for smartphones that synchronizes with the video camera and stores information in the Emercoin blockchain . Secondly, it is a set of algorithms and utilities that implement them, necessary for integration with third-party services. Thirdly, the Proof smart contract implemented on the basis of the Ethereum platform .
When using the Prover application, users will always have access to information stored in the blockchain, such as:
In the Emercoin blockchain, the formation of the swype code is carried out based on the hash of the last block in the chain, the address of the client of the blockchain network and other necessary information. After the video is completed, the hash of the received video file is calculated. The hash is stored in the Emercoin blockchain together with the block number on the basis of which the swype is generated, as well as the identifier of the mobile device that the video was shot.
Where can all this come in handy?
Anyone will soon be able to invest in Prover technology: the crowdsale will be implemented within the Ethereum ecosystem. Investors will be able to purchase Proof tokens at a fixed rate, getting the right to use the services of the service for free or at a discount, and also claim for a part of the funds accumulated by the Proof smart contract in proportion to the number of tokens in the total issue.

Thirdly, the Proof smart contract implemented on the basis of the Ethereum platform .
When using the Prover application, users will always have access to information stored in the blockchain, such as:
- date and time of receipt of the individual swype code;
- generated swype code;
- hash of the video data file (the video data file itself is stored by the user);
- The date and time the hash was loaded.
In the Emercoin blockchain, the formation of the swype code is carried out based on the hash of the last block in the chain, the address of the client of the blockchain network and other necessary information. After the video is completed, the hash of the received video file is calculated.

Where can all this come in handy?
- Auto insurance (CASCO) - in the event of an insured event, the client will be able to present a video certified by the Prover system as evidence;
- Confirmation of authorship of a video - by recording a video, the user can permanently assign ownership of it to her and be able to confirm it;
- Remote monitoring of patients - clinics and insurance companies will be able to confirm that the patient received proper therapy in full. The patient will be able to prove that he properly complied with all the instructions of the doctors;
- Online games and quests - Prover technology is embedded in mobile applications, allowing you to register the onset of gaming events;
- Progress reports - remote inspection of work (construction, installation, cleaning, patrolling, courier delivery, etc.) .;
- Fixing traffic violations and public order - time, date and place of recording video evidence for provision to law enforcement authorities;
- Educational projects - remote user identification and verification of their actions within the educational platform;
- Legal video messages - protection and confirmation of video messages without an in-person visit to officials.
