Development of a New Advance Encryption Scheme, a Potential Solution to Security Risk in Cloud Computing
In a joint development by NTT and Mitsubishi Electric Corporation, Mitsubishi Electric made an announcement on development of new Novel encryption technology addressing security risk in cloud computing paradigm. The new scheme is a fine-grained encryption capable of sophisticated and fine-grained data transmission and access control. The new scheme uses a mathematical approach known as “dual pairing vector spaces”.
In fine-grained encryption various parameters are added to the ciphertext and decryption key in the encryption-decryption logic, where attributes and predicates on them become the parameter of the ciphertext or decryption key. Read more
Development of Spatial Audio Transmission Technology for Mobile Phones
NTT DoCoMo has unveiled a newly developed spatial audio transmission technology for mobile phones capable of assigning a spatial position to each sound source when a user is listening to multiple sound sources for example during a game or a conference call. Through this technology the user is able via the headphone to hear each speaker’s voice as if they were coming from a unique direction creating a virtual face-to-face communication environment. DoCoMo’s planned target for this newly developed technology is for use in mobile conference calls, tele-education and online games according to DoCoMo. Read more
Development of fastest variable focus lens by NTT
Basically a variable focus lens is a zoom lens in which focal length is variable where elements inside a variable focus lens shift their position, enabling the lens to change its focal length so one lens can have many focal length. The newly developed variable focus lens which incidentally is based on KTN (potassium tantalate niobate, KTa1-xNbxO3) is claimed by NTT-AT (NTT Advance Technology) to be 1000 times faster than the existing PZT (piezoelectric zirconate titanate) base variable focus lens.

Development of power bar for DC distribution
Fujitsu component and NTT facilities Inc. made a joint announcement on development of long awaited commercial version of power bar and power plug. The power bar and plug are designed for 400V high voltage direct current distribution system. The two companies successfully solved technical problems with arc discharge from open/close circuits plus its effect on human body which was hampering the commercialization of this product. Read more
Intelligent microphone from NTT
Here is an interesting product from NTT which comes right out of a James Bond movie. As you all know the conventional microphones that we use for recording purposes are deigned to pick up various surrounding noises within its range instead of picking up a specific sound that you might be interested in. Well, don’t get any wrong ideas, no spying on your significant others. Well, here is a new intelligent microphone that NTT has been developing which is capable of picking up only the specific targeted sound by cutting off other unwanted surrounding noise. Read more
Quantum computers fiction or reality
For those of you not familiar with the subject of quantum computers it is a device just like the conventional computers to make computation with a help of superposition and entanglement phenomena as part of what we know today in quantum mechanics. The basic idea is to use these phenomena in performing operation on data as well as representing data. The operation is performed on QUBITS otherwise known as Quantum Binary Digits. Read more
