VIRTUAL CURRENCY ADDRESS SECURITY

1 . A memory device having instructions stored thereon that, in response to execution by a processing device, cause the processing device to perform operations comprising:

obtaining a first public-private key pair;

receiving over an electronic network public keys of two or more second public-private key pairs; and

generating a digital currency address using the public keys of the two or more second public-private key pairs and a public key of the first public-private key pair.

2 . The memory device of claim 1 , wherein one of the second public-private key pairs is generated by a different electronic device than a different one of the second public-private key pairs.

3 . The memory device of claim 1 , wherein the operations further comprise:

encrypting a private key of the first public-private key pair using a secure token;

obtaining an encrypted version of only a subset of private keys of the two or more second public-private key pairs, wherein the encrypted version is generated using an authentication object; and

causing the encrypted version of the private key of the subset to be electronically stored.

4 . The memory device of claim 1 , wherein the operations further comprise:

in response to receiving a withdrawal request corresponding to the generated transaction, transmit over an electronic network the encrypted private key of the second public-private key pair for decryption using the authentication object; and

in response to receiving a transaction, using the secure token to sign the transaction.

5 . The memory device of claim 1 , wherein the operations further comprise:

in response to receiving a withdrawal request corresponding to the generated transaction, transmit over an electronic network a notification for decryption of the encrypted private key of the second public-private key pair using the authentication object; and

in response to receiving a transaction, using the secure token to sign the transaction.

6 . The memory device of claim 1 , wherein the operations further comprise:

obtaining an additional third public-private key pair; and

generating an additional digital currency address using the public keys of the two or more second public-private key pairs and the public key of the additional third public-private key pair.

7 . The memory device of claim 6 , wherein the operations further comprise:

receiving a request for a third party deposit that is associated with a first identity that is different than a second identity corresponding to the generated digital currency address; and

generating the additional third public-private key pair responsive to receiving the request for the third party deposit;

wherein the additional digital currency address to be used for a transaction corresponding to the third party deposit.

8 . The memory device of claim 7 , wherein the operations further comprise sharing the public key of the additional third public-private key pair with the remote device or another remote device associated with the second identity.

9 . The memory device of claim 8 , wherein the operations further comprise:

encrypting a private key of the first public-private key pair using a secure token;

obtaining an encrypted version of only a subset of private keys of the two or more second public-private key pairs, wherein the encrypted version is generated using an authentication object; and

causing the encrypted version of the private key of the subset to be electronically stored;

wherein said sharing of the public key of the additional third public-private key pair is out of band with respect to a communication path used for said sharing of the encrypted version of only a subset of the corresponding private keys.

10 . The memory device of claim 8 , wherein said sharing of the public key of the additional third public-private key pair is by inserting said public key into a meta data field associated with the transaction.

11 . A method, comprising:

obtaining a first public-private key pair;

receiving over an electronic network public keys of two or more second public-private key pairs; and

generating a digital currency address using the public keys of the two or more second public-private key pairs and a public key of the first public-private key pair.

12 . The method of claim 11 , wherein one of the second public-private key pairs is generated by a different electronic device than a different one of the second public-private key pairs.

13 . The method of claim 11 , further comprising:

encrypting a private key of the first public-private key pair using a secure token;

obtaining an encrypted version of only a subset of private keys of the two or more second public-private key pairs, wherein the encrypted version is generated using an authentication object; and

causing the encrypted version of the private key of the subset to be electronically stored.

14 . The method of claim 11 , further comprising:

in response to receiving a withdrawal request corresponding to the generated transaction, transmit over an electronic network the encrypted private key of the second public-private key pair for decryption using the authentication object; and

in response to receiving a transaction, using the secure token to sign the transaction.

15 . The method of claim 11 , further comprising:

in response to receiving a withdrawal request corresponding to the generated transaction, transmit over an electronic network a notification for decryption of the encrypted private key of the second public-private key pair using the authentication object; and

in response to receiving a transaction, using the secure token to sign the transaction.

16 . The method of claim 11 , further comprising:

obtaining an additional third public-private key pair; and

generating an additional digital currency address using the public keys of the two or more second public-private key pairs and the public key of the additional third public-private key pair.

17 . The method of claim 16 , further comprising:

receiving a request for a third party deposit that is associated with a first identity that is different than a second identity corresponding to the generated digital currency address; and

generating the additional third public-private key pair responsive to receiving the request for the third party deposit;

wherein the additional digital currency address to be used for a transaction corresponding to the third party deposit.

18 . The method of claim 17 , further comprising sharing the public key of the additional third public-private key pair with the remote device or another remote device associated with the second identity.

19 . The method of claim 18 , further comprising:

encrypting a private key of the first public-private key pair using a secure token;

obtaining an encrypted version of only a subset of private keys of the two or more second public-private key pairs, wherein the encrypted version is generated using an authentication object; and

causing the encrypted version of the private key of the subset to be electronically stored;

wherein said sharing of the public key of the additional third public-private key pair is out of band with respect to a communication path used for said sharing of the encrypted version of only a subset of the corresponding private keys.

20 . The method of claim 18 , wherein said sharing of the public key of the additional third public-private key pair is by inserting said public key into a meta data field associated with the transaction.
