The speech recognition industry has begun to flourish in the industry, and smart speakers and smart driving are all in use. TracTIca estimates that the annual output value of the speech biometrics industry will approach $5 billion by 2024. According to the report, the voiceprint recognition has great potential.
Market research firm TracTIca estimates that the voice biometric industry will have an annual production value of nearly $5 billion in 2024, with application scenarios including border checkpoints, health care, credit card payments and wearables. CB Insights statistics show that at least 45 startups are currently developing speech recognition and self-driving related chips, at least five of which have raised more than $100 million.
Amazon Alexa Cloud Digital Assistant will have voiceprint recognition in the future to confirm user identity. For example, the user can set up, only his own voice ID (Voice ID) can start the credit card shopping function. Amazon CEO Jeff Bezos revealed in his interview that Echo smart speakers, Alexa cloud digital assistants have a dedicated development team of thousands of people, and have been working hard for nearly four years before the service went live.
According to CTA, sales of US voice-activated smart speakers (including Amazon Echo and Google Home) increased by 279% in 2017, and it is estimated that this year's market will increase 60% year-on-year to 43.6 million units, and sales will increase 93% year-on-year. 3.8 billion US dollars. At the same time, sales of US connected devices will increase by 6.6% year-on-year to 715 million units in 2018.
However, HSBC published a research report in May last year, pointing out that less than 50% (46%) of respondents believe that fingerprint recognition can replace passwords and trust iris recognition is only 26%. 70% of the respondents rely on traditional passwords for identification, much higher than fingerprint recognition (21%) and voiceprint recognition (6%).
According to foreign media reports, confidential documents provided by the National Security Agency (NSA) broketer, the NSA confidential memo in January 2006 showed that US intelligence units had voiceprint recognition technology at the time, which could be used to monitor terrorists and politics. People, drug lords, spies, and their own employees. Although the outside world knows that NSA relies on fingerprints and face recognition technology to find the target of locking, the 2008 internal document shows that voiceprint recognition is the most powerful part of this unit.
Mining is the process of creating a block of transactions to be added to the Ethereum blockchain in Ethereum's now-deprecated proof-of-work architecture.
The word mining originates in the context of the gold analogy for cryptocurrencies. Gold or precious metals are scarce, so are digital tokens, and the only way to increase the total volume in a proof-of-work system is through mining. In proof-of-work Ethereum, the only mode of issuance was via mining. Unlike gold or precious metals however, Ethereum mining was also the way to secure the network by creating, verifying, publishing and propagating blocks in the blockchain.
Mining ether = Securing the Network
Mining is the lifeblood of any proof-of-work blockchain. Ethereum miners - computers running software - used their time and computation power to process transactions and produce blocks prior to the transition to proof-of-stake.
