Desarrollo de base de datos Jobs

In modern times, we are realizing more than ever that some of the most important and valuable information that a company can have is its data. We know that a company’s reputation can be compromised through a data hack or leak, and that often times, the right intellectual property can add millions, or even billions, of dollars, to the market capitalization of a corporation. As a result, companies both big and small should be doing everything that they can to keep their data safe.

Database developers work to make sure that databases where information is stored is as efficient and flexible as possible, to make sure that no matter what happens, companies can have their data safe, in any situation. The right database developer can make sure that this is done at the lowest cost possible, and also avoid storing redundant data, which obviously makes operations less productive and efficient.

No matter what, data is essential. We know that Big Data is one of the biggest technological trends in the world, because it helps to illuminate information, whether it’s regarding consumer trends or scientific research. A database developer understands the important of keeping information safe, which is essential in modern times.

    Social media users generate tremendous amounts of data. To better serve users, it is required to share the user-related data among researchers, advertisers and application developers. Publishing such data would raise more concerns on user privacy.

In this work, we propose a new adversarial attack specialized for social media data. We further provide a principled way to assess effectiveness of anonymizing different aspects of social media data. Our work sheds light on new privacy risks in social media data due to innate heterogeneity of user-generated data which require striking balance between sharing u...
