Sharemind HI (Hardware Isolation)

Services with end-to-end data protection

In a service powered by Sharemind, data owners encrypt their data on premises and upload them to Sharemind. The host of a Sharemind server cannot decrypt the values or learn anything from them. However, Sharemind can process the data without removing the protection or having access to confidential values. All results will be encrypted as well. This is called Computation on Encrypted Data or Runtime Encryption.

In addition, Sharemind ensures that no unauthorized query can be performed and only authorized users can provide data or see results. Logs are kept of all activities to keep track of queries and users.

Built-in confidentiality with Sharemind HI

The Sharemind HI Application Server provides an Application Programming Interface (API) for implementing privacy-preserving services using Trusted Execution Environments. Sharemind HI keeps track of applications, their authorized users and data.

Apps running on Sharemind HI use its APIs to request access to data. Sharemind HI enforces that each user can perform activities according to its roles. All accesses are controlled and logged by Sharemind HI.

A key feature of Sharemind HI is the standard library of privacy-preserving data analysis algorithms designed for use in Trusted Execution Environments with limited memory access. This feature allows Sharemind HI to support big data applications that balance privacy and performance.

Powered by Intel® SGX

Sharemind HI uses the Software Guard eXtensions (SGX) technology by Intel to create Trusted Execution Environments. Sharemind HI makes extensive use of the attestation feature provided by SGX. Sharemind HI customers can receive proofs that a server is running the correct versions of Sharemind HI and its applications.

Sharemind HI supports special enforcer clients who can enable or disable an application remotely based on information provided by Sharemind HI. This information can include the configured roles and software versions, but also audit logs.

Cookie Policy of sharemind.cyber.ee

This document informs Users about the technologies that help this Website to achieve the purposes described below. Such technologies allow the Owner to access and store information (for example by using a Cookie) or use resources (for example by running a script) on a User’s device as they interact with this Website.

For simplicity, all such technologies are defined as "Trackers" within this document – unless there is a reason to differentiate.
For example, while Cookies can be used on both web and mobile browsers, it would be inaccurate to talk about Cookies in the context of mobile apps as they are a browser-based Tracker. For this reason, within this document, the term Cookies is only used where it is specifically meant to indicate that particular type of Tracker.

Some of the purposes for which Trackers are used may also require the User's consent. Whenever consent is given, it can be freely withdrawn at any time following the instructions provided in this document.

This Website uses Trackers managed directly by the Owner (so-called “first-party” Trackers) and Trackers that enable services provided by a third-party (so-called “third-party” Trackers). Unless otherwise specified within this document, third-party providers may access the Trackers managed by them.
The validity and expiration periods of Cookies and other similar Trackers may vary depending on the lifetime set by the Owner or the relevant provider. Some of them expire upon termination of the User’s browsing session.
In addition to what’s specified in the descriptions within each of the categories below, Users may find more precise and updated information regarding lifetime specification as well as any other relevant information — such as the presence of other Trackers — in the linked privacy policies of the respective third-party providers or by contacting the Owner.

There are various ways to manage Tracker related preferences and to provide and withdraw consent, where relevant:

Users can manage preferences related to Trackers from directly within their own device settings, for example, by preventing the use or storage of Trackers.

Additionally, whenever the use of Trackers is based on consent, Users can provide or withdraw such consent by setting their preferences within the cookie notice or by updating such preferences accordingly via the relevant consent-preferences widget, if available.

It is also possible, via relevant browser or device features, to delete previously stored Trackers, including those used to remember the User’s initial consent.

Other Trackers in the browser’s local memory may be cleared by deleting the browsing history.

With regard to any third-party Trackers, Users can manage their preferences and withdraw their consent via the related opt-out link (where provided), by using the means indicated in the third party's privacy policy, or by contacting the third party.

Locating Tracker Settings

Users can, for example, find information about how to manage Cookies in the most commonly used browsers at the following addresses:

Users may also manage certain categories of Trackers used on mobile apps by opting out through relevant device settings such as the device advertising settings for mobile devices, or tracking settings in general (Users may open the device settings and look for the relevant setting).

Consequences of denying consent

Users are free to decide whether or not to grant consent. However, please note that Trackers help this Website to provide a better experience and advanced functionalities to Users (in line with the purposes outlined in this document). Therefore, in the absence of the User's consent, the Owner may be unable to provide related features.
