Proximity based content sharing

A computer-implemented method comprising:

• receiving, by the receiving device of a receiving user, a notification broadcast by a sharing device based on a sharing user requesting to share a content item and the receiving device being within a limited broadcast range of the broadcast, the notification broadcast by the sharing device without using contact information of the receiving device or the receiving user to broadcast, the content item stored in a first namespace with a content management system, the first namespace associated with the sharing user, and the notification broadcast according to a short-range communication standard having the limited broadcast range;
• obtaining, by the receiving device, based on the notification an encrypted token comprising an encrypted identifier for the content item, the encrypted token encrypted based on a password provided by the sharing user to the sharing device;
• responsive to obtaining the encrypted token, prompting, by the receiving device, the receiving user to provide the password;
• decrypting, by the receiving device, the encrypted token based on the password to generate a decrypted token, the decrypted token comprising an unencrypted identifier for the content item;
• and
• transmitting, by the receiving device to the content management system, the decrypted token and a request that the content item be added to a second namespace with the content management system, the second namespace associated with the receiving user of the receiving device.

A computer-implemented method comprising:

• receiving, by a sharing device from a sharing user, a request to share a content item stored in a first namespace with a content management system, the content management system remote from the sharing device, the first namespace associated with the sharing user;
• receiving, by the sharing device from the sharing user, a password associated with the request to share the content item;
• responsive to receiving the request and the password, generating, by the sharing device, an encrypted token comprising an encrypted identifier for the content item, the encrypted token encrypted based on the password;
• broadcasting, by the sharing device, a notification with a limited broadcast range, the notification broadcast by the sharing device without using contact information of a receiving device or a receiving user to broadcast;
• establishing, by the sharing device, a short-range connection with the receiving device of the receiving user that received the notification;
• and
• transmitting, by the sharing device to the receiving device via the short-range connection, the encrypted token, the receiving device configured to prompt the receiving user to provide the password and to decrypt the encrypted token based on the password to generate a decrypted token, the decrypted token comprising an unencrypted identifier for the content item for the content item to be added to a second namespace with the content management system, the second namespace associated with the receiving user of the receiving device.

A non-transitory computer-readable storage medium storing instructions that, when executed by a computing system, cause the computing system to perform operations comprising:

• receiving, by a sharing device from a sharing user, a request to share a content item stored in a first namespace with a content management system, the content management system remote from the sharing device, the first namespace associated with the sharing user;
• receiving, by the sharing device from the sharing user, a password associated with the request to share the content item;
• responsive to receiving the request and the password, generating, by the sharing device, an encrypted token comprising an encrypted identifier for the content item, the encrypted token encrypted based on the password;
• broadcasting, by the sharing device, a notification with a limited broadcast range, the notification broadcast by the sharing device without using contact information of a receiving device or a receiving user to broadcast;
• establishing, by the sharing device, a short-range connection with the receiving device of the receiving user that received the notification;
• and
• transmitting, by the sharing device to the receiving device via the short-range connection, the encrypted token, the receiving device configured to prompt the receiving user to provide the password and to decrypt the encrypted token based on the password to generate a decrypted token, the decrypted token comprising an unencrypted identifier for the content item for the content item to be added to a second namespace with the content management system, the second namespace associated with the receiving user of the receiving device.
