# Datashare

## Overview

The DataShare service is used to share data with other entrusted services and partners. The mechanism shares are the following:

1. Retrieves and stores data to be shared in [Object Store](/1.2.0/id-lifecycle-management/supporting-components/persistence/object-store.md) and returns a Datashare URL.
2. It fetches data from the Object Store when the Datashare URL is called.

The sharing of data is controlled by the [Datashare policy](/1.2.0/id-lifecycle-management/support-systems/partner-management-services/pms-existing/partner-policies.md#datashare-policy).

Data is encrypted before sharing it with partners. Learn more about [datashare encryption](/1.2.0/readme/principles/privacy-and-security/data-protection.md#datashare).

The relationship of Datashare Service with other services is explained here. *NOTE: The numbers do not signify the sequence of operations or control flow. Arrows indicate the data flow.*

1. ABIS Handler Stage creates datashare for ABIS.
2. Manual Adjudication Stage creates datashare for adjudication.
3. Verification Stage creates datashare for verification.
4. Datashare Service calls [Policy Manager Service](/1.2.0/id-lifecycle-management/support-systems/partner-management-services.md#policy-management-service) to get the policy for creating shares.
5. It calls the [Keymanager](/1.2.0/id-lifecycle-management/supporting-components/keymanager.md) Service to encrypt data as per policy.
6. Stores datashare inside [object store](/1.2.0/id-lifecycle-management/supporting-components/persistence/object-store.md).
7. Retrieves datashare from the object store when the datashare URL is called.
8. External systems like [ABIS](/1.2.0/id-lifecycle-management/supporting-components/biometrics/abis.md), Print System, Adjudication system etc. calls Datashare Service to get the datashare.
9. Print Service creates UIN PDF and uploads to datashare through Credential.
10. [Partner Manager Service](/1.2.0/id-lifecycle-management/support-systems/partner-management-services.md) creates credentials for CA certificates to be used by [ID Authentication](/1.2.0/id-lifecycle-management/identity-verification/id-authentication.md).
11. Printing Stage creates credentials for printing systems and sends the data through datashare.
12. [ID Repository](/1.2.0/id-lifecycle-management/identity-issuance/id-repository.md) Service sends data to ID Authentication system through Credential.
