It is provided a method for providing data for training a machine learning model. The method is performed in a training data provider () and comprises the steps of: obtaining () a data structure comprising a chain of delegations, the chain of delegations covering a delegation path from a media capturing device () to the training data provider () such that, in the chain of delegations, each delegation is a delegation from a delegator to a receiver; sending () a key request to a delegation verifier (), the key request comprising the data structure; receiving () a decryption key from the delegation verifier (); obtaining () encrypted media data captured by the media capturing device (); decrypting () the encrypted media data, resulting in decrypted media data; and providing () the decrypted media data for training the machine learning model.

Providing data for training a machine learning model

According to a first aspect, it is provided a method for processing an input media feed for monitoring a person. The method is performed by a media processing device comprising a media capturing device. The method comprises the steps of: obtaining an input media feed using the media capturing device; providing the input media feed to a local artificial, AI, intelligence engine, to extract at least one feature of the input media feed; and transmitting intermediate results comprising the extracted at least one feature to train a central AI model, while refraining from transmitting the input media feed. The local AI engine forms part of the media processing device. The intermediate results comprise a label of the extracted at least one feature. The label is obtained from an end result of another local AI engine.

Processing an input media feed

It is presented a method for providing access to a lock for provision of a service. The method comprises the steps of: receiving a request for access to the lock, the request being based on the service consumer ordering a service requiring access to a physical space, the request comprising a first public key associated with a co-ordinator and a second public key associated with a service provider agent; presenting a first consumer query to the service consumer; receiving a first positive consumer response indicating that the service consumer allows the service provider agent to access the physical space; and delegating access to the lock to the co-ordinator, which comprises encrypting at least part of a delegation using the first public key, encrypting at least part of the delegation using the second public key, and electronically signing the delegation, enabling further delegation to the service provider agent.

Providing access to a lock by service consumer device

It is presented method for providing access to a lock for provision of a service. The method is performed in a lock manager and comprises the steps of: receiving a request for access to the lock, the request being based on the service consumer ordering a service requiring access to a physical space which is secured by the lock; sending a first consumer request to a service consumer device, asking whether to grant access to the lock for a service provider agent to provide the service; receiving a first positive consumer response from the service consumer device, indicating that the service consumer allows the service provider agent to access the physical space secured by the lock; generating a temporary credential for the service provider agent; providing the temporary credential to the service provider agent; and configuring the lock to accept the temporary credential.

Providing access to a lock for a service provider

It is provided a method for controlling access to a physical space. The method is performed in an access control device and comprises the steps of: communicating with an electronic key to obtain an identity of the electronic key; obtaining a plurality of delegations; determining, from one of the delegations, that there is an auxiliary condition, wherein the auxiliary condition is that access is approved for the electronic key by an auxiliary party, authenticated by a digital signature by the auxiliary party; and granting access to the physical space when the plurality of delegations comprises a sequence of delegations covering a delegation path from the access control device to the electronic key such that, in the sequence of delegations, the delegator of the first delegation is the access control device, the receiver of the last delegation is the electronic key, and the auxiliary condition is fulfilled.
