SurDoc Unveils TruPrivacy – New Technology Breakthrough Now Makes Cloud Storage Completely Private and Secure

Cloud Storage Provider, SurDoc, Gives Users 100 Percent Data Privacy Protection

MENLO PARK, California, Nov. 19, 2012 –/ — SurDoc, an innovator of cloud-based storage and document technology, today announced that consumers can now get TruPrivacy™ – a breakthrough development in cloud storage security technology – that provides absolute privacy protection for users, while keeping cloud storage provider costs low. With TruPrivacy, consumers now can confidently use cloud-based storage, knowing that their data and files are finally safe from hackers or any other unauthorized third-party, such as the government, industry associations, or even employees within a cloud service provider.

“As the cloud becomes the de facto storage center for personal as well as business data, it is critical that consumers and IT professionals understand that there are substantial risks of data leakage, exposure and even theft that go along with cloud-based storage,” said Alex Wang, CEO of SurDoc. “Data protection and privacy is paramount, and users want to be assured that their cloud storage service provider does not put sensitive data at risk. With TruPrivacy, these concerns are now moot.”

TruPrivacy – Changing the Way Files are Secured in the Cloud
Today, most cloud-based storage providers utilize a data storage technique called deduplication. Although highly efficient, deduplication is fraught with security and privacy holes that can expose customer files and their contents. However, coupled with TruPrivacy technology, data deduplication becomes highly secure whereby no one can access, view or share customer data.

For utmost security and privacy, most cloud storage providers encrypt customer data via an encryption methodology that uses an encryption key to encrypt customer data. Unfortunately, the mismanagement of these keys can lead to data loss, exposure or theft.

With TruPrivacy, SurDoc performs encryption in a way that has never been done before. Rather than always use a key to encrypt a file, TruPrivacy technology includes a step to use the file to encrypt the security key. As part of this, SurDoc invented a new algorithm to manage encryption keys, further ensuring that data is kept completely private.

With TruPrivacy, every file is encrypted with a unique encryption key, which is then encrypted before being stored on a server. As part of the TruPrivacy process, only the user who owns the file can calculate the encryption key; the server has no knowledge of both the encryption key and the unencrypted file. Because of this, only the user who owns the particular file can access their file.

Wang concludes, “As more personal and business information moves to the cloud, the risks of loss increase exponentially. Now with TruPrivacy, cloud storage providers can instill trust and confidence among their customers that sensitive data remains what people expect – secure and private.”
