Research on Content Consumption Monitoring System

Term Definition Distributed Ledger A database that does not rely on a central administrator or centralized storage, and data is replicated, shared, or synchronized to multiple nodes in the network. Blockchain A list of records linked in chronological order, using cryptography for security. Each block contains the hash value of the previous block, forming an immutable chain. Block A single unit of record in the blockchain, containing transaction data, timestamp, and hash value of the previous block. Transaction record An event recorded on the blockchain, such as a content consumption record, which contains a device identifier, content information, and timestamp. Smart contract A piece of code stored on the blockchain that is automatically executed when preset conditions are met, such as verifying and recording content consumption transactions. Encryption Converts information into an unintelligible form that can only be decrypted by someone with a key. Digital signature An electronic signature created using a private key that verifies the source and integrity of a message. Node Participants in a distributed network, such as content consumption devices or servers, can store a copy of the blockchain and verify transactions. Mining The process of verifying and adding new blocks to the blockchain by solving complex computing problems, and nodes are rewarded for successful mining. Ethereum Virtual Machine (EVM)The operating environment on the Ethereum blockchain that is used to execute smart contracts and process transactions. Content Consumption DeviceAny device that can access and consume content, such as a set-top box, smartphone, tablet, etc. Content ProviderAn entity that provides content, such as a cable company, streaming service, etc. Consumption RatingIndicators calculated based on content consumption data, such as the number of views, viewing time, user engagement, etc., used to evaluate the popularity of content. Targeted ContentPersonalized content recommended to users based on user profiles and consumption habits. Media Access Control Address Identifier (MAC ID)The hardware address used to uniquely identify network devices, such as smartphones, tablets, etc., can be used to identify the location of users and devices.

Short Answer Question

What is the difference between a distributed ledger and a blockchain?

A distributed ledger is a way of storing data in which data is copied, shared, or synchronized to multiple nodes in a network, while a blockchain is a specific type of distributed ledger that uses cryptography to ensure security and links a list of records in chronological order. Each block in a blockchain contains the hash value of the previous block, forming an immutable chain.

How does a content consumption monitoring system use blockchain technology?

Content consumption monitoring systems can use blockchain technology to create tamper-proof and transparent records of content consumption records. Each consumption record is stored as a transaction on the blockchain, which contains data such as device identifiers, content information, and timestamps.

What is the role of smart contracts in content consumption monitoring?

Smart contracts can automatically verify and record content consumption transactions. For example, when a user watches a specific channel or program, a smart contract can record the viewing time, channel information, and other relevant data and add this data to the blockchain.

How do content consumption monitoring systems protect user privacy?

Content consumption monitoring systems can protect user privacy by using anonymous identifiers instead of identifiers that can identify personal information. The system can also encrypt data to prevent unauthorized access.

What is a digital signature and how is it used in content consumption monitoring?

A digital signature is an electronic signature created using a private key to verify the source and integrity of a message. In content consumption monitoring, digital signatures can be used to verify the authenticity and integrity of content consumption records.

How do content consumption monitoring systems determine the consumption rating of content?

Content consumption monitoring systems can determine the consumption rating of content by analyzing content consumption records stored on the blockchain. For example, the system can calculate indicators such as the number of views, viewing time, and user engagement to evaluate the popularity of the content.

What is target content, and how does the content consumption monitoring system determine the target content?

Target content is personalized content recommended to users based on user portraits and consumption habits. The content consumption monitoring system can determine the target content by analyzing the user's viewing history, channel preferences, and other relevant data.

What is the role of MAC ID in content consumption monitoring?

MAC ID can be used to identify the location of users and devices, such as determining whether the user is at home or away. This information can be used to provide more relevant advertising and content recommendations.

How does the content consumption monitoring system reward participating users?

The content consumption monitoring system can use digital currency or other reward mechanisms to reward participating users. For example, users can earn rewards by watching ads, participating in surveys, or providing feedback.

What is the future development trend of the content consumption monitoring system?

Content consumption monitoring systems are likely to become more personalized and data-driven. With the advancement of artificial intelligence and machine learning technologies, the system will be able to more accurately predict user preferences and provide more relevant recommendations.
