A password bank is software that secures a place for web users to store unlimited passwords and user names. The program integrates voice biometric authentication (speaker recognition) with a minimum of three layers of data encryption. A password bank should not be confused with a password manager, which typically encrypts data (passwords), but utilizes a different mechanism than voice biometric for authentication. == Origins of password banks == The average web user needs to remember 6.5 passwords, leaving many users to try to cut corners.〔"Drowning in Passwords? You're Not the Only One," by Kendra Srivastava. Mobiledia, March 12, 2012. http://www.mobiledia.com/news/131786.html〕 The challenge in remembering all of these passwords tends to invoke one of two actions: changing passwords on a regular basis, or to use a single password for all websites (which really defeats the purpose of passwords for security - an attacker need only break one password to harvest your entire online identity). Password cracking is an issue professional organizations are protecting themselves against. In June 2011, the storage service Drop Box failed to protect password authentication for a period of four hours, exposing the files of 25 million users.〔“Dropbox Left User Accounts Unlocked for 4 Hours Sunday,” by Ryan Singel, Wired, June 20, 2011. http://www.wired.com/threatlevel/2011/06/dropbox/〕 The Ponemon Institute surveyed 830 information technology, security, and compliance professionals. Over half of them cited emails as the main cause of data leaks.〔“Email Fingered As Main Source Of Data Leaks,” by Fahmida Y Rashid, Tech Week Europe, September 22, 2011. http://www.techweekeurope.co.uk/news/email-fingered-as-main-source-of-data-leaks-40451.〕 As a result, industry experts continue to seek out alternatives to standard passphrase authentication systems. Opus Senior Analyst Researcher Dan Miller said that “Voice biometrics strikes the right balance between strong authentication and usability.”〔“Voice Biometric to Play a Key Role In Security in 2012,” Elephant Talk News, January 18, 2012. http://www.infosecurity-magazine.com/view/23332/voice-biometrics-will-be-the-authentication-of-choice-says-opus-research/.〕 Opus Research in connection with ValidSoft concluded that “the conditions are ripe for the emergence of voice biometrics as the dominant means of authentication, particularly for financial transactions. The key drivers are the growth of mobile banking and e-finance together with the intrinsic lack of security on mobile devices. A secure means of authenticating mobile devices is an increasing necessity.”〔"Voice biometrics will be the authentication of choice, says Opus Research," Infosecurity, January 19, 2012, http://www.infosecurity-magazine.com/view/23332/voice-biometrics-will-be-the-authentication-of-choice-says-opus-research/.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Password bank」の詳細全文を読む スポンサード リンク
