Molecular-level similarity search brings computing to DNA data storage

Inner Workings: DNA for data storage and computing.

On the surface, genetic and electrical engineering appear to have little in common. One field revolves around carbon and the other is built upon silicon; one makes RNA from DNA and the other converts AC to DC. But some creative biologists have begun to apply the concepts of electrical engineering to living cells. “We view ourselves as biological programmers,” says Timothy Lu, a member of the Sy...

Nanomaterials: DNA brings quantum dots to order.

An important goal in nanotechnology is to construct elaborate superassemblies of nanoscale components while maintaining strict control over the organization of these building blocks. Among the various types of potential building blocks are quantum dots, which are the focus of much research because they have unique optical and electronic properties that could prove useful in applications such as...

Similarity Search in Structured Data

Recently, structured data is getting more and more important in database applications, such as molecular biology, image retrieval or XML document retrieval. Attributed graphs are a natural model for the structured data in those applications. For the clustering and classification of such structured data, a similarity measure for attributed graphs is necessary. All known similarity measures for a...

Data Storage in Cloud Computing

With the development of cloud computing, outsourcing data to cloud server attracts lots of attentions. To guarantee the security and achieve flexibly fine-grained file access control, attribute based encryption (ABE) was proposed and used in cloud storage system. However, user revocation is the primary issue in ABE schemes. In this article, we provide a ciphertextpolicy attribute based encrypti...
