Evolution of key technologies
Traditional character verification ➜Compound behavior verification
According to the iResearch 2023 report, the penetration rate of compound verification codes in enterprise applications has increased by 42% compared with 2020, and the verification failure rate has dropped by an average of 18 percentage pointsImplementation Recommendation Outline
Key points for implementation in the banking industry
Adopt the compound verification mechanism design with the highest security capability index (recommended ratio): - Behavioral characteristics account for 60% - Knowledge verification accounts for 30% - Human-machine pop-up window interval is 180 secondsBest practices for e-commerce platforms
It is recommended to establish a product knowledge base based on the NLU algorithm, trigger the question-and-answer verification interface when the user visits the core business node, and use the pseudo-random recommendation algorithm to reduce the crawler reuse efficiency.Sample only — not a preview of GB/T 41802-2022
